SOLAR STEAM GENERATION FOR

COOKING - SYSTEM

Home uses 85-90 LPG cylinders per month

Increase in LPG price

Approx LPG cost increase Rs.80,000 per month

Promise of solar thermal as renewable energy with

storage

Why ARUN100?Need to cook 2800 meals/day -- breakfast, lunch, evening snacks and dinner – 700 each

Early Morning Cooking - 4.30 am

Steam Storage needed

Uninterrupted Steam Supply at any time

Quick steam generation in the morning

Automated Dual Axis SUN Motion Tracking

Mirror arrangement: Fresnel Paraboloid concentrator with a point focus

Automated water pumping, steam storage

Steam output: 540kg/clear sunny day

Up to 7 bar pressure

20-25kg LPG saving/day

Produced Steam is Stored as Pressurized Hot Water in a 2000 Litre Tank CALLED ACCUMULATOR.

ARUN100 DISH PROVIDES QUICK STEAM SUPPLY

104 sq meter in Area and 100% indigenously develope d Fresnel Parabolic Solar concentrator

Ministry of New and Renewable Energy, Government of India, provide 30% financial subsidy for the project.
