Innovation through Design

FIRED HEATERS

Thermic fluid heaters allow temperatures over 280^oC for various process applications.  Guha Industries has these innovations to their credit 

• Separate expansion and de-aeration vessels to ensure that relatively cold oil in handled in the expansion tank - preventing thermal oil oxidation for longer life.

• A membrane wall design with straight tubes (rather than coils) ensures lower thermic fluid pressure drop and lower pump power consumption.  We can offer multiple starts, and flexible flow rates - unlike coil designs that need another external pump for flow dilution.

• An air pre-heater to ensure proper furnace oil combustion and efficiency up to 92%, by reducing the stack temperature to 180^oC, even with a process fluid temperature above 250^oC.  

• A cyclonic combustion system for solid fuels that can take most organic fuels like firewood, coal, lignite, rice husk, coconut husk, etc. 

Our pressurized hot water boilers operate up to 180^oC, completely within a closed loop, eliminating the need for water treatment plants required by steam boilers.  Presently, pressurized hot water systems are also exempted from boiler regulations.  

The choice between thermic fluid heaters and hot water systems is determined by the operating temperature.  Above 160oC, the higher cost of the pressure vessels for the pressurized hot water system makes thermic fluid more attractive.  However in critical process applications where inflammable fluids are a concern, hot water systems would be the preferred choice.

For dryers, indirect hot air generators can provide 300^oC and above by fuel oil combustion
