The so-called power plant boiler, in general, is the boiler used by the power plant to generate electricity. Generally, the capacity is relatively large. The current main unit is 600MW, and the most advanced is the ultra-supercritical boiler with a capacity of 1000MW. There are two main types of power station boilers: pulverized coal boilers and circulating fluidized bed boilers. These two types of boilers are the main types currently used in power stations. The biggest difference between a fluidized bed furnace and a pulverized coal furnace is the state of the fuel, that is, liquid and pulverized coal.
Power plant boilers, also known as “power plant boilers”, refer to medium and large boilers in power plants that provide steam turbines with a prescribed quantity and quality. One of the main thermal equipment in thermal power plants. It is often matched with a certain capacity steam turbine generator set, mainly used for power generation, but can also be used for external heating in some special occasions. Generally, its evaporation capacity is large and the steam parameters (steam temperature and steam pressure) are very high. A complete set of auxiliary equipment is required. It is necessary to configure a chamber combustion furnace and adopt forced ventilation. It can burn a variety of fuels (coal, crude oil or heavy oil, Blast furnace gas or coke oven gas) has a complex structure and high efficiency, most of which can reach about 85-93%. It has very high requirements for operation management level, mechanization level and automatic control technology.
