The diagnosis system detects bias type errors from mass, material, and energy balances (Korpela, 2014, Huovinen, 2012). In thermal power plants e.g. combustion air, fuel, and flue gas flows are connected with each other via balance equations and this relationship can be used to check the consistency of the measured process values.

The most commonly used fuels are coal, natural gas, and oil. There are three main types of steam boilers: Fire tube, water tube, and cast iron. The diagram below shows the components of a fire tube boiler. In fire tube boilers, the combustion gases travel within the tubes to heat the surrounding water. Fire Tube Boiler Diagram.

1. Introduction. Combustion is one of the key processes at thermal power plants (TPPs) [Citation 1].The efficiency and availability of the entire TPP depend on its adequate control [Citation 2–5].A good solution for the control task results in many benefits, such as robust maintenance of steam parameters, reduced environmental pollution, less …

mainly used for thermal power generation. In a thermal power plant, the BFP is one of the criti-cal auxiliary machines that are equivalent to the heart of the plant. In thermal power generation, high-pres-sure steam is used to drive a turbine, which in turn ro-tates the generator directly connected to the turbine to generate power.

In many existing coal-fired plants equipped with volumetric feeders (such as those in the UK), there is a gradually growing appreciation of the economic and environmental benefits of gravimetric feeders and undoubtedly conversions will eventually occur. ... Modern Power Systems is a product of Progressive Media International. …

Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.
