Power generation in thermal power plants is a kind of power generation method which converts the fuel into electricity by burning in the boiler to generate steam to drive the operation of the generator set. Power generation from coal-fired boilers is the most common kind. Boiler in thermal power plant generally adopt clean coal combustion technology of coal circulating fluidized bed boilers.
Coal-fired CFB boiler for power generation in thermal power plants has incomparable environmental advantages: When the bed temperature is maintained between 800-900℃, the desulfurization reaction efficiency is the highest, and the desulfurization rate of up to 80%-90% can be obtained under the appropriate Ca/S ratio and limestone particle size. By controlling the mixture of fuel and air, the emission of nitrogen oxides can be reduced. With dust treatment device, the dust emission is also very low.
This series of CFB boiler is equipped with membrane water-cooled wall hanging furnace and separator inlet is membrane water-cooled flue. Adopt bell hood with easy replacement, low resistance and no dust pouring. The separator and the center barrel are improved with low resistance and high separation efficiency. Adopting the patented reverse material device and equipped with an independent fan for air supply, saving power consumption. Boiler in thermal power plant also adopts low bed pressure operation mode, stable and reliable operation. The primary fan with lower pressure head is used to reduce the power consumption of the fan.
It reduces the pressure head of the secondary fan through advanced manufacturing experience, optimized secondary air layout and nozzle flow rate. The air preheater of the boiler product adopts multi-tube box arrangement, and the low-temperature section adopts corrosion-resistant steel pipe, so as to avoid the overall replacement caused by low temperature corrosion. The sealing performance is good, the output is sufficient to receive the surface arrangement is fully reasonable, the boiler temperature increases the pressure quickly. Large load adjustment range, can be in 30-110% load stable operation.
Good anti-wear performance of coal-fired boilers in thermal power plants. Special anti-wear materials and construction are used in the furnace. Environmental desulfurization efficiency is high, and the separation efficiency is 99% when the combustion is full. Wide adaptability of various inferior coal and coal gangue can burn well. At the same time, it has a high degree of safety automation. The operation of the boiler adopts remote and near ground monitoring, automatic control and monitoring instruments are complete, safe and reliable, easy to operate. Combining industrial automation control technology, Internet technology, computer software and artificial intelligence technology, the industrial boiler Internet of Things platform can realize remote human-computer interaction and data sharing.
The boiler in thermal power plant introduction and absorption of advanced production experience, reliable water circulation, high combustion efficiency, low pollution emission. Its superheater, economizer and air preheater are arranged in the aft shaft. The technology of high temperature separation of fly ash and internal circulation fluidization reburning of fly ash make boiler combustion more sufficient.
