Flue gas temperature regulation coal-fired power generation boiler and operation method

Abstract

The invention discloses a flue gas temperature regulation coal-fired power generation boiler and an operation method. The flue gas temperature regulation coal-fired power generation boiler comprises aboiler body, a control box, a reaction tank, a connecting pipe, a sleeve, a fixing assembly and a circular ring baffle. The reaction tank is arranged on one side of the bottom of the boiler body. Thecontrol box is welded to the top of the reaction tank. The connecting pipe is arranged at the center of one side of the reaction tank. The circular ring baffle is welded to one end of the connectingpipe. The sleeve is welded to the outer side of the circular ring baffle. The sleeve is located on one side of the connecting pipe. Threaded holes are correspondingly formed in the two sides of the sleeve. The flue gas temperature regulation coal-fired power generation boiler and the operation method have the beneficial effects that the structure is simple, the operation is convenient, the traditional direct sleeving fixing is abandoned, mounting and dismounting are convenient, user maintenance and replacement of a generator conduit are facilitated, the time and labor are saved, and the laborintensity of workers is lowered; and meanwhile a compression spring is used for providing elastic force, so that the generator conduit is prevented from being disengaged from the sleeve when subjectedto external impact or shaking in use, and sleeve connection and fixing are facilitated.

Description

technical field [0001] The invention relates to the technical field of power generation boilers, in particular to a flue gas temperature-regulated coal-fired power generation boiler and an operating method. Background technique [0002] The so-called power generation boiler, generally speaking, is a boiler used by a power plant to generate electricity. It is one of the main thermal equipment of a thermal power plant. It can also be used for external heating. Generally, it has a large evaporation capacity and high steam parameters. It needs a complete set of auxiliary equipment. Most of them need to be equipped with a chamber combustion furnace. It adopts forced ventilation and can burn a variety of fuels, such as pulverized coal, crude oil or Heavy oil, blast furnace gas or coke oven gas, etc., have a complex structure and high efficiency, most of which can reach about 85-93%, and have relatively high requirements for operation management level, mechanization degree and auto...

[0002] The so-called power generation boiler, generally speaking, is a boiler used by a power plant to generate electricity. It is one of the main thermal equipment of a thermal power plant. It can also be used for external heating. Generally, it has a large evaporation capacity and high steam parameters. It needs a complete set of auxiliary equipment. Most of them need to be equipped with a chamber combustion furnace. It adopts forced ventilation and can burn a variety of fuels, such as pulverized coal, crude oil or Heavy oil, blast furnace gas or coke oven gas, etc., have a complex structure and high efficiency, most of which can reach about 85-93%, and have relatively high requirements for operation management level, mechanization degree and automatic control technology; traditional power generation boilers have complex structures , the operation is cumbersome, and the generator conduit is directly connected by socketing. This connection method is difficult to install and disassemble, which increases the labor intensity of workers, and is not conducive to the user's maintenance and replacement of the generator conduit. Cause the pipe to fall off, which is not conducive to the user's use; in view of these defects, it is necessary to design a flue gas temperature-regulated coal-fired power boiler and its operation method
