hydraulic for hotwater boiler
Jinzhou construction and installation company needs an electric heating hot hydraulic for hotwater boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
The reasons for failure of imported gas boiler Analysis: Our country is a developing country, is also the world's production of boilers and boiler use than any other country. In recent years, although economic development, people are increasingly aware of the harm caused by pollution, with the implementation of the western development strategy, the environmental protection department of coal-fired boiler renovation project, due to the abundant gas resources, less pollution, so the gas boiler has been It has been widely applied to various industries, not only production, but also our lives. Gas boiler installed in our country, some is imported boilers, but sometimes there will be substandard imported boiler problems, is this why? Qingdao Tsing Yi gas boiler resolve to solve this problem.
Henan gas boiler for producing a comprehensive analysis of the structure of a gas boiler gas boiler Co quick combustion is a horizontal three-pass fire tube boiler steam gas. Henan internal gas boiler furnace with a bias wet back structure, high temperature flue gas flushing of sequentially and two third return pipe tobacco, and then discharged into the atmosphere through the chimney of the smoke chamber. Zhengzhou boiler front cover with smoke flow, the boiler to facilitate inspection. Arrangement boiler burners function well, using automatic combustion ratio adjustment, feedwater automatic control, start-stop procedure to improve the older technology, automatic operation, etc., and having a low water level and low level alarm, high vapor pressure, flame automatic protection function. the boiler has a compact, safe, reliable, easy to manipulate, rapid installation, low pollution, low noise, high efficiency main features: A, reasonable overall structure Henan gas boiler, compact, is a boiler island, in line with the premise of this quick product consists of three departments; boiler host, and chimney. piping system, wherein the host and the manufacturing sector has completed stack in the workshop, the host supporting the pipes and valves, the meter has been properly installed randomly transported to The host site and to assemble the chimney. Site gas supply is turned on, power supply, water line to test. Shorten the installation period, and can ensure the quality of products .B Henan gas boiler functions designed to improve their predecessors. The overall structure of the boiler host genus , the burner assembly of the smoke front cover, the main body and a combustion chamber heating surface arranged sectors having reasonable structure, compact, low consumption of steel, with a bias waveform furnace furnace, the insulation layer is made of new lightweight insulation materials, packaging using a color sheet, a rectangular parallelepiped shape of the package, the boiler performance, weight, frame size, appearance and domestic products compared with the capacity to improve their predecessors have significant perception of beauty. the boiler water supply apparatus disposed in the right side of the boiler so that the base of the boiler and the host as a whole, do not have to do another foundation.
Main steam temperature in the boiler when a hot start is less than the rated Why? Hot Start For the boiler itself, in fact, is to a certain stage of the whole process of Cold Start as a starting point. When the unit stopped running, the boiler cooling faster than the turbine. If the turbine is in a semi-hot or warm, cold boiler may already start operation of such boilers essentially as cold to warm, boosting, to try to meet the red hot state turbine revolutions required parameters for input large amount of fuel, but this time only by the amount of the bypass system and a steam exhaust air is not enough, so that the steam temperature rises rapidly, and the walls and high temperature. Also, because the combustion chamber and the flue outlet larger width, uneven temperature distribution in the furnace, the superheater tubes are not circle the steam flow rate, the temperature difference is large, causing local over-temperature superheater tubes. To prevent over-temperature superheater, extending its life, so to start the predetermined process in the main steam temperature should be lower than the rated 50 ~ 60 ℃.
