chain grate coal steam generator

Xuedong Academy of Sciences, has presided over the national key scientific and public relations projects, provincial and ministerial level more than 10 key research projects, National Science and Technology Progress Award 3, provincial and ministerial level scientific and technological progress award 11, published more than 60 papers. Has won the ninth China Youth Science and Technology Award, the third national outstanding scientific and technological workers, Chinese Mechanical Engineering Society of Youth Science and Technology Award and the honorary title, is the first and second level candidates national "millions of Talents Project." Twenty years of development, the Group, through remote monitoring system in the field of gas combustion wealth accumulated a wealth of data, it would be gold mine of knowledge for future cooperation;

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 chain grate steam generator 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.

9.Steam from the steam drum is sent to the primary super-heater.

10.Steam is super heated to a high temperature and pressure in the primary super-heaters and then moves to the secondary super-heaters.

11.In the secondary super-heaters steam meets the very hot gases exiting the top of the boiler. The steam is heated to its final temperature and pressure before leaving the boiler as main steam. The main steam is sent to the high pressure steam turbine. The steam turbines drive a generator which produces electricity.

12.Steam exiting the high pressure steam turbine is called cold reheat. It is reheated in the re-heater and sent back to the second steam turbine. By the time the flue gas exits the boiler most of the energy in the coal will be transferred to the water in the boiler. The hot gases are cleaned up before they are sent to a stack. Feed-water is generally supplied by condensed steam from the low pressure steam turbine. Large amounts of cooling water are used to condense this steam into liquid water in the condenser.

What is zero meters boilers and boiler which can not be in the ground? Learn and understand this important site on the boiler products, the following will be continued, because this is all hope, this can deepen their familiarity with the product, and at the same time, the depth of which can also make their own, and not stay on the surface, which can affect their learning process, as well as all the proper use of the boiler, as well as their results. 1. three hundred and fifty thousand generators, they are supporting the boiler capacity, how much it is? And, what is the net efficiency of the boiler? Three hundred and fifty thousand generators, they are supporting the boiler capacity, under normal circumstances is to 1024t / h, its vapor pressure, it is 17.9MPa. As for the efficiency of the boiler by which the heat is effectively utilized in this basis, calculated to its specifically, it is the individual energy as heat input, and on this basis, to be calculated.
