2020/3/24 · Direct Boiler Efficiency = Heat output / Heat Input X 100. Or. Direct Boiler Efficiency = Q X (h2 – h1) / (q X GCV) X 100. Here, Q = Qty of steam generated. h2 = Enthalpy of steam at the output of the boiler. h1 = Enthalpy of feed water. Heat Input = q X GCV. q = Fuel Qty.

The concept of burning coal that has been pulverized into a fine powder stems from the belief that if the coal is made fine enough, it will burn almost as easily and efficiently as a gas. The feeding rate of the pulverized coal is controlled by computers, and is varied according to the boiler demand and the amount of air available for drying and transporting fuel.

2012/11/10 · Coal is preferred for PCC boilers that have properties ketergerusan with HGI (Hardgrove Grindability Index) above 40 and the water content of less than 30%, and the ratio of fuel (fuel ratio) is less than 2. Combustion with the PCC method will produce ash which consists itself of clinker ash as much as 15% and the rest of the fly ash.Figure 5.

The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding device (speed variator of coal feeder) directly.

In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.

2020/9/4 · This boiler heats up water to the boiling point with a combustion process. The combustion is done by using fuel sources. This combustion produces heat in a tube that's submerged in water. The heat is rejected to the system as the "steam" which flows in the pipes that are connected to the outlet and the equipment that is being heated by
