suijitupian87.jpg" />Coal-fired boilers are responsible for approximately 30% of these emissions, and thus, represent the largest source category ( Salvesenejt §1., 1978). The typical flue gas composition of coal-fired boilers is provided in Table 1. This is based on 3.5% sulfur, 16% ash coal, 10,500 Btu/Lb. and an excess air rate of approximately 25%.

BOILERS Bureau of Energy Efficiency 27 Syllabus Boilers: Types, Combustion in boilers, Performances evaluation, Analysis of losses, Feed water treatment, Blow down, Energy conservation opportunities. 2.1 Introduction A boiler is an enclosed vessel that provides a means for combustion heat to be transferred into water until it becomes heated water or steam.
suijitupian151.jpg" />Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork

suijitupian164.jpg" />Types of Coal. There are various types of coal, from anthracite with its high carbon content to bituminous coal, subbituminous coal and lignite (brown coal), which is an even younger coal. Power generating equipment needs to be optimized for these different types of coal. Mitsubishi Power is able to supply the optimum power generating equipment

suijitupian41.jpg" />Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
