Modern power plants have an extensive electrical distribution system to provide reliable power to all of the support equipment in the power plant. The utility operating the power plant is in the business of generating electrical power twenty four hours a day, seven days a week. Since electrical power can not be
widely used on coal-fired power generating facilities. The trend is expected to continue at least for the next couple of decades. Conditioning the fly ash in the flue gas is an established technique used to improve- restore the performance of an ESP in coal-fired power plants with high-resistivity fly ash resulting from burning low sulphur coals.

• Facility's heat-to-power ratio: If the heat-to-power ratio in the facility is higher than that for the cogeneration plant, the excess steam demand is usually met by utility boilers. Any saving in steam demand (by better heat recovery) saves fuel in the utility boilers and leaves the operation of the cogeneration plant unchanged.

Guidance on Best Available Techniques and Best Environmental 3.3 Co-benefit enhancement techniques fired power plant boilers are mostly single-fuel, while coal-fired industrial boilers often are designed for and use a more diverse mix of fuels (e.g., fuel by-products, waste, wood) in addition to coal (Amar
Bottom ash or boiler slag derived from lignite or sub-bituminous coals has a higher percentage of calcium than the bottom ash or boiler slag from anthracite or bituminous coals. Although sulfate is not shown in Table 4-2, it is usually very low (less than 1.0 percent), unless pyrites have not been removed from the bottom ash or boiler slag.
During the last decade, construction of new fossil power plants has come to a virtual halt in the United States. The main factors responsible for this situation are: (1) industry perception of the existence of sufficient reserve margins, (2) uncertainty in forecasting load growth, (3) cost of borrowing for new plant construction, (4) siting and licensing problems for new plants, and (5) the
When a power plant or an individual power generating unit experiences a gradual increase in load, or a sudden but mild overload, the unit governors will sense the resulting speed change and increase the power input to the generator. The additional load is handled by using the spinning reserve; that is, the unused capacity of the generator.

Any boiler burning anything other than natural gas will produce build up and require boiler deslagging. Oil, coal, biomass, and waste fuels all create ash, which accumulates on the outside of the boiler as slag. Boiler deslagging is a method of removing these pollutants, which typically result in the reduction of harmful emissions, mitigating
Efficiency. With the ideal design of the heating surfaces we achieve the highest possible energetic utilisation of the waste-to-energy plant. The economiser surfaces are also optimally arranged, in order to make maximum use of the heat from the flue gas, while also reduce the exhaust gas temperature.
