industry diesel gas steam generator
The basic configuration of the heat of the gas steam boiler steam boiler and service method is natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace released heated pot water, and allowed to vaporize into steam heat conversion equipment. Water in the pot is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the expansion of the water vapor inside limited dynamic pressure generated heat is formed as an energy source is widely used. Steam boiler fuel burn-up and to ensure that the flue gas outlet temperature was cooled to a safe value convection heating surface of the work; using the heat of the flue boiler feedwater heating, in order to reduce exhaust gas temperature, fuel economy and functions. Each industry diesel steam generator heating surface and joined together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. Gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. Water temperature should be close to the furnace temperature. Must regularly inspect the low water cutoff maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. Require periodic sewage operation, at least once a day, after the sewage drain valve should be checked because of possible contamination and leaks; if it must be excluded. When shutdown is not maintained while the steam pressure, the steam space of the boiler will produce negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened.
1. The pressure test the electrical components of the electrical industry diesel 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.
Thermal power plant boilers provide steam to turbine generator, including boiler and ancillary equipment. The fuel in the boiler furnace release heat energy after combustion, so that the heat be transferred to water in the boiler through the metal wall into the superheated steam with a certain pressure and temperature, and then fed the steam to turbine, the steam turbine drive generator to generate power.
To proceed from reality, should be in accordance with the electric power, gas should the gas, the coal should be coal, should be hot the thermal principle, promote the use of all kinds of clean energy for winter heating cleaning. In order to reduce air pollution and protect people's warm winter as a foothold to enterprises, government promotion, residents can withstand the principle of gas after the first change to gas will change in gas assurance, the price is acceptable on the basis of sound promote the "coal to gas" and central heating engineering, in district heating supply pipe network can not cover, vigorously implement the replacement of coal-fired power heating project.
Good job of marketing system storage capacity for natural gas. Accelerate the construction of natural gas transmission and distribution network, the new natural gas volume priority for life and severe winter areas of urban air pollution and coal for heating alternative. In principle, to new natural gas cogeneration and gas chemical projects.
Accelerate agricultural and pastoral areas "coal to electricity," the process of upgrading the power grid. Coordinate development of power transmission project construction, etc. are encouraged to promote the regenerative electric heating. Around on the "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.
In accordance with national requirements, shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
According to air quality improvement requirements to accelerate the delineation of high-pollution fuel combustion zone ban and to expand the scope of, and actively promote the elimination of small coal-fired boilers. The county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers and tea furnace, stove and other operating coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, other areas on no new 10 tons of steam per hour of coal-fired boilers. While banned out of coal-fired boilers, pressure boilers market regulators cancellation of registration certificate to use.
