direct-fired systems. The biomass fuel is burned in a boiler to produce high-pressure steam that is used to power a steam turbine- driven power generator. In many applications, steam is extracted from the turbine at medium pressures and temperatures and is used …

Get a quoteFire tube boilers are subdivided into three groups. Horizontal return tubular (HRT) boilers typically have horizontal, self-contained fire tubes with a separate combustion chamber. Scotch, Scotch marine, or shell boilers have the fire tubes and combustion chamber housed within the same shell. Firebox boilers have a water-jacketed firebox and

For example, a boiler can fire at its maximum of 2 million BTU/hr rate when the heat load is highest, then gradually turn down as low as 4% (80,000 BTU/hr) as load decreases.

Analysis shows, however, that up to 500 MW CFBC plants hold a thermal and economic advantage over PC plants even when fired with premium fuels, and that this advantage is enhanced by their ability to fire low-cost 'opportunity' fuels.

This is what is today known as a three-pass boiler, the fire heating the underside, the gases then passing through a central square-section tubular flue and finally around the boiler sides.
