MWS Solar Field ™ for IPH

(A) Background



Introduction to Industrial Process heating
About 70% of energy produced in the industry is used for generating heat in form of hot water, steam, heated oil, etc. And about 56% of this falls within temperature range of up to 400°C.

Industry Working Fluids Temperature Range
Pharmaceutical Industry Steam, Air 80°C - 230°C
Textile industry Water, Steam 60°C - 150°C
Chemical Industry Steam, Air 80°C - 320°C
Pulp & Paper Industry Steam Up to185°C
Food Industry Steam, Air, Thermic Oil 80°C - 280°C
Mechanical Industry Water, Steam 60°C - 150°C
Automobile Industry Water, Steam 60°C - 200°C
Air Conditioning (VAM) Water, Steam 60°C - 150°C
 
Industry Working Fluids Temperature Range
Laundry Steam 150°C - 180°C
Cooking Steam, Food Grade Oil 120°C - 280°C
Cleaning, Bathing Water 50°C - 65°C
 
Industry Working Fluids Temperature Range
Boiling Steam 150°C - 180°C
Baking Food Grade Thermic Oil 120°C - 240°C
Frying Food Grade Thermic Oil 200°C - 250°C
Washing Utensils Hot Water Up to 45°C
 

Common fuels to meet these heating need are Coal, Wood, Furnace Oil, Electricity, Natural Gas, LPG, etc. Current key pain points related to fuel selection for the industry:

  • High fuel cost (Mining, Transportation & Material Ash handling)
  • Primitive and inefficient fuel burning Techniques
  • Contamination of process due to flue gas from burning fuels

 

(B) Solution

MWS Paraboloid Solar Thermal Dishes uses paraboloid Concentrating Solar technology to deliver high temperatures for Industrial Process Heating applications. Water/Oil coming toreceiver gets heated by this concentrated sunlight.

MWS Solar Fieldconsists of network of interconnected MWS Solar Dish Concentrators which deliver heat energy. MWS Dishes have automated two axis Sun-Tracking mechanism to ensure highest thermal efficiency & energy output from reflector. MWS Solar Fieldcan be scaled from one to hundreds of dishes as per requirement, and can be retrofitted to existing industrial systems. MWS Solar Field is 100% indigenous solution, made in India.

"India’s lightest true paraboloid solar concentrator with no Dead weights, no counter weights required"

Working Principle of MWS Solar Field

  • MWS Paraboloid Dish Concentrator consists of reflectors of solar grade mirrors, a cavity receiver and two-axis solar tracking system
  • The incoming radiation gets concentrated by reflectors on to the receivers which carries working fluids such as hot water, thermic oil, etc.
  • Energy output from each receiver is routed by a piping system for integration into an industrial process
  • Fully automated double axis tracking system ensures maximum energy collection and highest energy yield to displace maximum fuel consumption

MWS Solar Field for Direct Heat Delivery
Process fluid is directly heated in the solar concentrator to integrate with the customer end process

MWS Solar Field for Indirect Heat Delivery
Solar field heats up working fluid (thermic oil) and delivers heat to customer end applications by use of heat exchangers. Its benefits are:

  • Mechanical isolation of both heating circuits
  • Thermal coupling
  • Same solar field can be used for a variety of end process applications such as hot water, hot air, thermic oil heating etc.
