5000 kg gas steam generators
Another technology being incorporated by boiler manufacturers is the gas turbine.When a gas turbine is used, natural gas is fired, and the hot gasses are used to spin a turbine attached to an electrical generator to make electricity.Since there is still available heat in the gas that exhausts from the turbine, it is then sent through a Utility Power HRSG (Heat Recovery Steam Generator).Similar to a watertube boiler, the hot exhaust gasses from the turbine heat water in the tubes of the utility power HRSG and turn it into steam, which is then used to turn a second steam-driven turbine attached to another electrical generator.This technology is called “Combined Cycle Cogeneration”, and is a very efficient use of fuel because the same fuel source is used twice to drive turbines.
Select natural gas boiler when security issues are important natural gas heating boiler is to protect human health and indoor warm, so the choice of natural gas boiler when security issues are important, but the quality can not be ignored, and only with good quality, was more at ease when in use, some services also can do better, choice of heating is customer satisfaction. Learn natural gas boiler certainly need to know the sales of the product, and if it shows good reputation natural gas boiler in the comprehensive aspects are still very good, worthy of consumer choice, performance, and thermal energy conversion can consult, when such use was not there will be problems when installed, do not worry voltage is not enough. Gas boiler shutdown method: after stopping a powder, a duct for 5 minutes and then purged to stop the gun. Oil gun should be purged one by one, not at the same time purging multivessel oil gun. After completion of purging gun oil, natural ventilation of the boiler furnace 5 to 8 minutes, 20 ~ 30% of the air volume is not less than the rated load. To exclude combustible material remaining in the furnace. Different power ratings differ 5000 kg steam generators relief valve, the rated steam pressure less than or equal to 3.82MPa steam generator valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm; pipe connecting the boiler safety valve, which cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve; valve should normally be installed exhaust pipe , exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. The bottom of the safety valve exhaust pipe should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. Steam generator safety valve should meet the following requirements: Rated evaporation is greater than 0.5t h boiler /, at least two safety valves installed; equal to or less than the rated evaporation boiler 0.5t h /, mounted on at least a safety valve. The separable at the economizer outlet, the outlet of the steam generator safety valve must be installed. Valve should be mounted vertically in a high position in the pot business, set box. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and a valve; lever-type safety valve should prevent the movement of the self-weight of the lever means and the limiting guides deviant, to spring safety valve there lifting handle means and preventing movement of the adjustment screw is screwed lightly.
SHENGSHUI large diameter cylindrical vertical potshell early fuel boiler steam boiler biomass boiler manufacturers _  [boiler] biomass boilers, biomass boilers, steam boilers custom small, high gas 5000 kg steam generators Tonglu customization steam generators, boilers and other special bath. The large-diameter cylindrical water storage boiler shell vertical energy saving, the appearance of fine, automated process, excellent service. Biomass boiler volume must be born on the 18 th century, the British steam engine boiler coal use substances, including J. Watt, including early steam engine, the steam pressure used is equal to the atmospheric pressure. After the second half of the 18th century above atmospheric pressure instead of steam. Early steam boiler is a boiler fuel biomass boilers of the 19th century, the commonly used steam pressure increased to about 0.8 MPa. Boiler with this adaptation, early steam boiler is filled with water to a large diameter cylindrical vertical potshell, then switch to a horizontal boiler shell, a fire is burning furnace brick shell below the pot. With bigger and bigger boiler, installed in the fire tube boiler shell, the front end light a fire in the fire tube, the flue gas from the back of the fire tube, the exhaust chimney and the external heating by the boiler shell brick flue, known as fire tube boiler. Cylinder means only starts a fire, a fire tube boiler or called single boiler Connie Hsu; was applied to two fire extinguishers, fire tube boilers or called double Lancashire boiler.
Recently, the market supervision bureau Zhoushan Development and Reform Commission and the relevant district towns, streets and CMC, 35 steam tons / hour and below the coal-fired boilers situation within the region to conduct a comprehensive diagnostic investigation, and to develop in accordance with the relevant requirements of provinces the remediation plan, renovation of existing enterprises to carry out classification boiler eliminated.
Accelerate the phase-out of coal-fired boiler renovation work is to win the Battle of the sky, to lay an important task for the campaign of prevention of pollution. In recent years, Putuo District of Zhoushan City, to speed up the adjustment of energy structure, and actively encourage enterprises to adopt "coal to gas," "coal to oil" as well as central heating and other measures. By the end of 2018, the district has completed the elimination or modification for 10 steam tons / hour coal-fired boilers 175 units, effectively promote pollution reduction work.
According to "Zhejiang win the Battle of Blue Sky three-year action plan" requirements, by 2020, the province will be basically eliminated 35 tons of steam / hour and coal-fired boilers, more than 35 steam tons / hour of high pollution and energy-saving ultra-complete boiler low-emission transformation. Next, our region will be based on the unified arrangements of provinces and cities, and actively practice the concept of green development, continue to promote the 10-35 tons of steam / h coal-fired boiler out of rectification work to further improve the air quality in Putuo District.
