In general, fluidized bed boilers can substitute higher levels of coal with biomass than pulverized coal-fired or grate-fired boilers. Fluidized bed boilers can handle biomass with higher moisture content (10%–50% instead of <25%) and larger particle sizes (<72 mm instead of <6 mm) than pulverized boilers (Agbor et al., 2014). They can

Coal is fed onto one end of a moving steel chain grate. As grate moves along the length of the furnace, the coal burns before dropping off at the end as ash. Some degree of skill is required, particularly when setting up the grate, air dampers and baffles, to ensure clean combustion leaving minimum of unburnt carbon in the ash. 2. Boilers

Mar 12, 2012 · The fire tube boiler was created in the 1800s, Fig. 1.7.Its main use was to run steam engines for motive power. One of the first brand names for this type of boiler was the Lancashire boiler, which used two parallel fire tubes. It was used to power steamboats and railroad engines and to run industrial machinery via belt drives.

Usually, the maximum heat input per burner is about 165 million Btu per hour. At full boiler load the secondary-air port velocity ranges from 4000 fpm for small boilers, where unheated secondary air is used, to 6000 fpm for a dry- ash-removal furnace with 600°F air. Velocities of 7500 fpm are common with circular burners in slag-tap furnaces.
