Solid Fuel Fired Three Pass IBR Steam Boiler

Boiler” means a pressure vessel in which steam is generated for use external to itself by application of heat which is wholly or partly under pressure when steam is shut off but does not include a pressure vessel .A 3-pass boiler design is the most efficient way to get the maximum amount of heat from the fuel. The design extracts heat from three times as much interior surface area of the boiler, compared to a single-pass, “pin-type” boiler design.
