Boiler Systems Operation. In steam heating systems, a boiler furnace heats water by means of a gas or oil-fired burner and turns it into steam. The steam travels through pipes to radiators or convectors, which give off heat and warm the room. As the steam cools, it condenses back into water, and returns to the boiler to be heated again.

Blowdown Heat Recovery Introduction. All steam boilers must blowndown to reduce the amount of TDS in the boiler water. See Blowdown However, along with the solids, boiler chemicals and thermal energy is lost; blowdown heat recovery systems cannot recover the chemicals, but they do recover up to 90% of the heat energy that would otherwise be lost down the drain.
heat recovery steam systems Selecting the appropriate "heat recovery steam generator" (HRSG) for cogeneration (CHP) and fume incineration systems involves much consideration. Important areas of concern are controlling/bypassing the waste heat, optimizing overall system performance, maintaining required operating pressures, boiler size, weight
The economics of a flash steam recovery system will depend on the amount of flash steam available and how much can be used that is currently not used in applications such as the deaerator. Operation. In the schematic to the right, the high pressure steam is passed through a PRV (Pressure Reducing Valve) at the top to form low pressure steam.
