Abstract: Feasibility study of Concentrated Solar Thermal Steam Cooking System has performed for climatic conditions of Delhi by taking the case of DTU boys hotel mess to replace LPG cooking system. Energy requirement for mass cooking in DTU mess is calculated to be 288981 KWh which till now is fulfilled by 15 LPG cylinders each of capacity of 14kg. An attempt is made to fulfill this requirement with solar energy using Scheffler Dish, although it is also known that complete energy requirement cannot be fulfilled due to unavailability of solar radiations at night, in monsoon and sometimes in winter. Almost 50% of energy requirement i.e.143880 KWh can meet by this system using 25 Scheffler Dish of 16m2. Calculations for CO2 emission due to burning of LPG in DTU hostel mess is also done which comes out to be 189 tonne and it is shown that with implementation of such a cooking system almost 50% of CO2 emission can be controlled. Effect of DNI, optical efficiency and temperature difference of feed water and steam is shown in this work. Cost of this project that is bear by DTU is around 62 lakhs with payback period of 2.84 years. This system has proposed with keeping in mind that it could prove a model to encourage other institutions in Delhi for implementing this technology for mass and collective cooking.
