Boilers | Why return condensate to the boiler? The best

Apr 21, 2010 · The benchmark for optimal condensate return is as high as 90%. This is possible if the plant doesn't use direct steam injection for process applications. Below is an illustration of the potential savings of a 44,000 lb/hr, 150 psig steam system with no condensate returned to the boiler plant: Dropping the make-up water quantity yields a

Frequently Asked Questions about Direct Contact Steam

Conventional boilers generate steam by heating water that flows through a collection of tubes inside the boiler. Heat is produced by burning fuel, which produces greenhouse gas emissions (GHGs), principally CO2. Flue gases from the boilers must also be treated to remove pollutants.

Tankless Coil and Indirect Water Heaters | Department of

An indirect water heater uses the main furnace or boiler to heat a fluid that's circulated through a heat exchanger in the storage tank. The energy stored by the water tank allows the furnace to turn off and on less often, which saves energy. An indirect water heater, if used with a high-efficiency boiler and well-insulated tank, can be the

Boilers - University of Alabama

Water-Tube Boiler (1867) A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water. The water tube diameter is much smaller than the shell diameter of a fire-tube boiler, so much higher pressures can be obtained, well over 2000 psi. The furnace and boiler tube area must be
