Steel Industry Solution
1Sammo Energy Ltd - Q1 2012
The Issue
The Steel industry is a very energy intensive industry. It uses furnaces at very high temperatures to prepare steel.Several types of furnaces are used:
• Blast furnaces and • Electric Arc Furnaces.
The new regulation on air pollutants will put an additional stress on this industry to maintain the NOx emission under every time lower levels.
The industry is permanently looking for ways of reducing their energy costs and consumption and reducing their emissions and carbon footprint.

Our business model
Sammo Energy Ltd is proposing to bring a full solution for the issue of the industry.
Sammo Energy proposes to invest on its own resources to bring the solutions to the industry using the following approach:
• Full solution implementation integrating power generation and batch preheating;• No investment needed from the industry, Sammo Energy makes all the necessary
investment from its own resources;• No adversary impact on the production process, the industry benefits only from the upsides;• Performing monitoring system follow up the benefits and performances of the systems;• Based on long term power purchase agreement guaranteeing a price of energy lower
than market price. The industry save money from the very first day of operation of the system;
• Base principle is to share all side benefits like carbon emission reduction incentives, grants, etc. All those programs are managed by Sammo Energy in full transparence;

Our Operational approach
In Steel making industry, all furnaces uses high temperatures and release large quantities of heat into the atmosphere one way or another wasting precious energy.
Our approach is the following:• Make a survey of all waste heat sources available with temperature above 150ºC;• Evaluate the coordinated way of using those sources of waste heat;
Based on the quantity of waste heat and its temperature, the optimum set of technologies will be selected:
• Organic Rankine Cycle Turbines;• Steam Rankine Turbines;• Kalina Cycle Turbines;• Other specific technologies;
The technologies used and their suppliers must be industry grade and demonstrate sufficient track record.
