SECTION – 6 TECHNICAL BID

1. Background

This project is targeted towards development and setup of indigenous 3.5 MWe x 24 hour/day Solar Thermal Power Plant. The research and development component of the targeted initiative was divided into several projects over the last 2 to 3 years. Each of these projects was formulated in tune with the overall perspective and handled independent of each other involving various faculty members across the departments at IIT Bombay.

Setting up of the above mentioned indigenous Solar Thermal Power Plant would now require development and testing of prototypes of various CSP components conceptualized till now and experimented with. This prototype development and testing is being taken up as three R&D projects mentioned below;

1. Linear Fresnel Reflector (LFR) based collector development with receiver and steam storage.2. Molten salt loop with central receiver, salt storage and heat exchanger.3. Heliostat reflector development with tracking and flux measurement.

These R&D projects are being taken up in parallel.

This Design Specification Document is for the LFRPCM project i.e ‘Linear Fresnel Reflector (LFR) based collector development with receiver and with PhaseChange Material (PCM) based steam storage’ which includes Development of Indigenous Efficient and Economical LFR system and Thermal Energy Storage. This project will be implemented at Greater NOIDA, Uttar Pradesh for testing and performance evaluation. After testing the setup online, the system is to be integrated to existing VAM of 50TR capacity.

1.1.Present Status of Technology

Size and configuration of LFR

LFR technology is a proven, mature and competitive technology with plant track record of over 200 MWe.

Typically, the LFR collector systems consist of reflector assembly consisting of elastically curved low iron glass reflectors. The width is constrained by the requirement of mirror curvature dictated by focal length, tracking accuracy demands and receiver width. Considering all these constraints, the configuration is selected for the present project.

The most of the LFR systems use multiple tubes receiver in India. Recently, single tube receivers with evacuated glass cover are being used globally as well as in India, which also require secondary reflector in the form of CPC mounted as a downward facing cavity. However, these evacuated tube receivers are comparatively costly. The multiple tubes receiver has more thermal losses when compared with the evacuated tube receiver mounted inside the secondary reflector mounted as a downward facing cavity enclosure.

In the present project, receiver with nonevacuated, glass covered single tube is proposed, that has reduced cost, without increasing the losses significantly.

Overall instantaneous collector EfficiencyThe typical mean optical efficiency of LFR is around 42% in most of the configurations. Presently, LFR technology with multiple tubes receiver has peak thermal efficiency of around 52% at the operating temperature of about 250˚C at the effective DNI of about 800 W/m2. With the improved receiver having nonevacuated, glass covered tubes this is expected to increase to about 55% without



compromising on the cost. Of course, at lower effective DNI, this is expected to reduce.

Cost of Thermal Energy Storage (TES)

Thermal energy storage includes a number of different technologies, each one with its own specific performance, application and cost. TES systems based on sensible heat storage offer a storage with efficiencies between 6090%, depending on the specific heat of the storage medium and thermal insulation technologies. Phase change materials (PCMs) can offer higher storage capacity per volume and storage efficiencies from 7590%. In most cases, storage is based on a solid/liquid phase change with energy densities of the order of 100 kWh/m3 (e.g. NaNO3). Thermochemical storage (TCS) systems can reach storage capacities of up to 250 kWhth/m3 with operational temperatures of more than 300°C and efficiencies from 75% to nearly 95%.

The cost of a complete system for sensible heat storage is up to 10/kWh€ th, or Rs.800/kWhth, depending on the size, application and thermal insulation technology. The costs for PCM and TCS systems are in general higher. In these systems, major costs are associated with the heat (and mass) transfer technology, which has to be installed to achieve a sufficient charging/discharging power. Cost of latent heat storage systems based on PCMs is up to 50/kWh€ th, or Rs.4000/kWhth, while TCS cost is up to 100/kWh€ th, or Rs.8000/kWhth,. The economic viability of a TES depends heavily on application and operation needs, including the number and frequency of the storage cycles.

Cost of LFR

Cost of solar field is in the range of 10,000 – 12,000 Rs./m2. The cost of the power plant can be significantly reduced by reducing the cost of the solar field per reflector area and by increasing the energy output per reflector area.

1.2 Goals

Development of Indigenous Efficient and Economical Linear Fresnel Reflector (LFR) collector system and Thermal Energy Storage (TES) with the following attributes:1. Overall instantaneous collector efficiency target: 55%@ 800 W/m2 DNI and 45%@ 500 W/m2

DNI, at the fluid operating temperature of about 250°C2. LFR system target cost of Rs. 8,000 to 10,000 per sq.m of reflector area is planned in long

run. This should be achieved for the large scale projects based on the learnings from the present project

3. Cost target for Thermal Energy Storage (TES): Rs. 3,500 per kWhth at 250 to 317°C

1.3 Objectives

To develop and demonstrate:1. Efficient, cost effective and indigenous LFR system for saturated steam2. Efficient, cost effective and indigenous LFR system for superheated steam3. Low cost indigenous Phase Change Material based Thermal Energy Storage (TES)4. Control scheme for integrating TES with LFR system5. Balance piping and piping accessories

2. Design Concepts and research approach

The basic technical design concepts, considerations and approach for components and / or subsystems are given below.



2.1 LFR solar energy collector System

A prototype of direct superheated steam generating LFR solar energy collector shall be developed and installed at the mentioned location to test and optimize various components such as primary reflectors, secondary concentrator, absorber tube with glass cover (with or without evacuation), support structures, tracking unit and control system designed for given process parameters like pressure as high as 108 bar in order to achieve high thermodynamic efficiency and low cost thermal energy storage system.

Primary Reflector of LFR will be optimally designed through ray tracing by considering the reflector parameters namely, geometry of primary reflectors, their size, spacing, radius of curvature as well as height of receiver tower. The project envisages use of secondary reflectors on LFR for better solar flux utilization. Secondary concentrator profile will be designed and optimized through ray tracing. The flux distribution on receiver and intercept factor will be estimated. Secondary reflector material will be selected for high reflectivity, thermal cycling and durability.The research will be carried out to ascertain the efficiency gains by using single tube absorber in such system. The experiment and analysis is to be carried out to assess the abovementioned efficiency gains. In addition, optimization of the system will be carried out. Single tube receiver of LFR will be designed based on the flux distribution around the absorber tube and comparison with ray trace analysis. Testing of stagnation temperature and heat loss of absorber tube will be carried out along with study of thermal stress of receiver tube and secondary reflector. Heat transfer and process parameter optimization will be carried out before finalizing the design. However the consultant shall carryout best option studies considering receiver with multiple tubes, evacuated tube and non evacuated tube with glass cover from the point of view of cost, possibilities of indigenization and performance. The final design for the receiver to be fabricated and demonstrated shall be based on the best option studies.

Efficient tracking system shall be designed with closed loop control system based on heat flux measurement. Reduction in auxiliary power requirement shall be achieved by increasing the effective collector area per tracking unit by coupling the modules.

Thermal Energy Storage (TES) shall be primarily based on pressurized water accumulator. Capacity of TES will be enhanced by use of PCM. The identification of PCM and design of the TES with PCM shall be carried out in this project. Phase Change Material for the Thermal Energy Storage (PCMTES) shall be selected based on allowable temperature range, material stability and corrosion properties. PCM module and steam accumulator shall be designed and optimized for operating pressure and size linked to cost. Simulation model shall be developed and studied to predict performance of PCMTES.

The process line shall be designed such that the feed water from the deaerator is pumped to the absorber tube of evaporator section where it gets heated up as it flows through the absorber tube. Saturated liquid steam mixture of dryness fraction of about 30% or higher will be obtained at the outlet. This saturated liquid steam mixture will be fed to a steam drum which separates the saturated steam and will be passed to the thermal energy storage unit and superheater section. The saturated liquid will be recirculated to the evaporator section using a recirculating pump. The schematic for the LFR–PCM prototype system is given in Figure 1. It shows the system process parameters of the LFR collector integrated with thermal energy system having provision for supplying saturated steam for heat exchanger as well as for operating VAM.

The sizing of the prototype shall be based on minimum water flow requirement and maximum allowable dryness fraction in the receiver for achieving acceptable level heat transfer coefficient inside the receiver tube. The performance design specifications for the prototype LFR system with evaporator and superheater are given in Table 1.

During testing of the prototype, steam output shall be targeted at 40 bar 376°C. After the



testing period, steam output shall be at 10 bar 180°C for supply to VAM over its lifetime of 25 years.

Figure 1: the schematic for the LFR – PCM system

2.2 Thermal Energy Storage System

A 2 GJ (555 kWh) PCMAccumulator based thermal energy storage (TES) module shall be developed and tested using the saturated steam produced by the LFR solar energy collector. Identification of suitable storage material, determination of thermophysical properties, corrosion studies of construction materials used in TES system, simulation of charging and discharging characteristics etc. shall be conducted to optimize the design of TES.

The PCM enhanced steam accumulator shall be designed to store thermal energy at a pressure of 108 bar that will be discharged in the form of saturated steam at 86 bar. The PCM module is to store 1.1 GJ (308 kWh) in the form of latent heat of salt and 0.9 GJ (247 kWh) in the form of sensible heat by the accumulator. The accumulator shall be designed to support the varying loads during the transient period of insolation.

The high pressure process line and its components shall comply with the ASME / IBR standards. PLCSCADA Controls and instruments will be suitably included to ensure stable operation of the system. The performance design specifications for the prototype TES system are given in Table 2.
