Safety Valve Of Steam Generator
The use of central heating hot water boiler is the best choice for winter heating in northern China. Shanxi Province is located in Chang Darrow Heating Co., Ltd. mainly provides heating and post-service maintenance of heating equipment, heating clients involved in enterprises and institutions, office buildings, residential housing and a variety of commercial and other entertainment venues. With the wide blue sky covered Battle of the project, China's gradual increase in the proportion of heating for cleaning, heating, Ltd. Dalong Chang respond positively to the call of national policy, high pollution intensity wishing previously used, low thermal efficiency of coal-fired boiler to replace the traditional use hot water boiler clean fuel. After comparing many boiler manufacturers, choosing the optimal selection, determined and professional cooperation parties do fast boiler fuel boiler cleaning equipment. Providing a fast side 35 MW gas tube hot water boiler (SZS35-1.6-Y.Q) according to their actual needs.
30 MW coal fired power plant boiler working principle
30 MW Coal-fired power plant boilerproduce electricity by burning coal in a boiler to heat water to produce steam. The steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.
Combined heat and power (CHP) introduction
Cogeneration, refers to the heat and power plant in the same joint together, shorted as CHP (combined heat and power). CHP plants have been ordinary waste heat to be utilized to provide cheap heating heat for industrial and household use, which can greatly improve the thermal efficiency. Typically thermal power, its efficiency is about 30 to 35%. This means that for every 1 mega-joule energy output, there are two mega-joules of heat wasted. This part of the heat of re-used to heat water, fully meet the heating needs of the plant and the residential area near the plant. CHP usually drive a steam turbine generator, and the exhaust heat is used to complement the existing boiler plant, the total efficiency of up to 80%.
1. The pressure test the electrical components of the electrical safety valve of steam generator if the steam generator is completely assembled (i.e., as good as the boiler and the header connecting pipe, tube, heating the surface of the assembly line and the like). Header pressure test and assembly line can not, if they have been made in the component parts and hydraulic test or an ultrasound test of 100%, or other non-invasive test similar words. Upon completion of the processing of these components assembled, pressure is applied to test weld inspection no damage (radiation or ultrasound) to the full-length flaw detection. 2. All of the tubes, welded, cast, shaped parts and components, not all of the processing done in the hydrostatic test steel. Said component members of the hydrostatic test is not necessary, if they have done 100% ultrasonic testing or other similar NDT inspection. Superheater and economizer; while allowing the individual parts and components subjected to the hydraulic test in combination together with the electric boiler, not separate discrete electrical steam generator installation if reprocessing or hydrostatic test words. Included in the scope of the hydrostatic test all of the electrical steam generator, superheater, economizer, steam generation and processing power of the finished part. After working on the fixed plant boiler, is delivered to the sub-mounting parts, components, assemblies dispersion transportation, so the installation must be pressure test. Hydrostatic test purpose is to check electrical steam generator, superheater, economizer all density and strength member, all other members must also be welded hydrostatic test.
