The Circulating fluidized bed coal fired total heating surface area of boiler contains mainly particles of an inert material, like sand and ash, including particles of SO2 sorbent. The coal content in a fluidized bed is not considerable, it is only from 3 to 5% of the whole mass of the bed.
Saturated vapor pressure gas steam total heating surface area of boiler is how strong is the replacement gas is typically adjusted to replace Cube saturated vapor pressure. Increase in natural gas, gas steam boiler heat storage capacity increase in a greater number of saturated steam occurs, so that the pressure increases, natural gas will lead to reduction of the saturation vapor pressure weakened. Second, the replacement gas steam boiler reveal the degree of closure of the auxiliary valve saturated steam piping may be replaced with saturated vapor pressure (valve opening pressure ambassador weakened, so that the valve off a small pressure increase)
