wns oil or gas boiler manufacturer

To the end of October 2020 to complete Chaigai coal-fired wns oil or boiler manufacturers no longer give financial awards complement.

Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.

A rated working pressure of the wns oil or boiler manufacturer steam pressure in the boiler should be greater than the sum of the plate for the steam production required for the pipeline resistance and operating pressure. Do not neglect the steam pipe resistance, because the higher rated steam pressure, saturated steam temperatures will also increase. Second, the boiler heating surface heating surface (heat transfer area) is an important boiler (design) parameters. Because of the large output of Boilers generally large overload capability; otherwise, output is small. Same boiler capacity, a relatively large heating area, a lower exhaust gas temperature, the higher the efficiency of the boiler, fuel combustion heat is more fully utilized, consumes less. Third, boiler blowdown boiler blowdown is clean the inside, remove the sludge, reducing the effective measures of scale. Fourth, the construction furnace boiler furnace tube diameter is also one of the very important (design) parameters. After a lot of boiler running for some time in the furnace coke, smoke pipe soot accumulated soot, black smoke even began, will be a waste of fuel. The main reason is the diameter of the furnace small, atomized oil particles had a chance to be injected into the combustion furnace wall caused by high temperature carbonization. Thus, when selecting a gas boiler furnace to select a larger diameter.

A few days ago, Datong City, Shanxi Province, issued a "decisive battle 300 days, to enhance the" Datong blue "plan", combined with ongoing Shanxi Province: innovation, work for "the great debate, promote green development, and constantly improve the level of ecological civilization, achieve a good number of days 300 days throughout the year for more than two goals. details are as follows.

1, aspects of the transition. On the basis of the regulation last year, continued to carry out "dirty scattered" enterprise rectification work. According to industrial policy, industrial layout planning, as well as land, environmental protection, quality, safety, energy consumption, etc., to carry out an intensive investigation, the establishment of management accounting. In accordance with the principle of "first stop after the rule", the implementation of classification disposal, have been banned "dirty messy" business, appears to prevent the resurgence of the phenomenon.

2, corporate governance aspects. Industrial pollution discharge standards to strengthen the comprehensive management of enterprises can not achieve full compliance, should be taken to stop production remediation. Full completion of key industries pollution remediation work, on the basis of the city's nine power companies that run on ultra-low emissions stable, GD Datong Power Generation Co. Ltd. within the scope of the built-up area of ​​the city and Datang International Yungang Thermal Power Co., Ltd. completed before the end of the colored Amidst the governance feasibility report, we lay the foundation for next year colored misty rain governance. December 30, 2019, to carry out ultra-low emissions and chemical industry, iron and steel, nonferrous metals, cement industry, especially emission limits transformation; completed 100 industrial enterprises fugitive emissions control, industrial furnace control 41 upgrades, 11 key industries and enterprises volatile organic compounds governance and four key industries and enterprises volatile organics management upgrade.

3, less coal ways. Insist on proceeding from reality, should be in accordance with the electric power, gas should the gas, should the coal coal (ultra low emission), should be hot is hot, and more heating energy policy to ensure the safety of the masses warm winter. Residents living coal simultaneous implementation of clean energy alternatives. District heating flat built-up area clean 100% coverage, coverage of other counties clean heating built-up area of ​​more than 70%, 40% or more in rural areas, to proceed with the phase-out of coal-fired boilers. Renovation project to carry out ultra-low emission coal-fired boilers, October 1, 2019, 65 tons of steam coal and above and build the region (biomass) and energy-efficient boilers to complete the transformation of ultra-low emissions, low nitrogen gas boiler basically completed the transformation.

Structural characteristics and rational utilization of the power of the furnace structure characteristic electric wns oil or boiler manufacturer hydraulic computing There are two methods for electrical boiler furnace: a designing new electric boiler, first by combustion requirements, according to the selected grate area of ​​the heat strength and the furnace volume heat intensity, determined baked and a preliminary discharge area is determined that the furnace volume, structure and size. Two boilers according to preliminary estimation method is recommended to determine the area of ​​the grate and furnace volume. Now Yaoan claim preliminary heat radiation heating surface arranged in the furnace, and the furnace structure is arranged drawn sketch, thereby performing the furnace structure characteristic calculation. When checking the conventional electric boiler furnace, if its structure is known, the furnace must be characteristic calculation means. Electric boiler furnace structure characteristic calculation means provide the necessary data for the furnace heat. After the furnace when the heat transfer calculation, checking furnace exit gas temperature is unreasonable, the institutions respond to the furnace and the radiation heating surface is arranged to be modified, and then calculated. The surrounding electric boiler furnace volume: Wall roof and around the center line of the plane (if the waterwall tubes covered with a refractory coating live bricks, where the surface is not Wall for Xianghuo arranged to the furnace wall surface of the wall. outlet chimney at the top of a row of tubes centerline) and a bottom surface of the plane. Unavoidable presence of various types of hydraulic oil flowing through the hydraulic valve when the pressure drop and flow loss, energy loss in this portion of the large proportion in the total energy loss. Therefore, a reasonable selection hydraulic, a pressure adjusting valve is also an important aspect of power loss reduction. Flow valve flow rate adjustment system according to the range of the minimum select and ensure stable flow can meet the requirements, the pressure in the pressure valve satisfied hydraulic equipment work properly, try to get a lower pressure. A reasonable choice of hydraulic oil. When the oil flow in the pipeline, will exhibit a viscosity, while too high viscosity, will have a greater internal friction, resulting in heating oil, while increasing the fluid flow resistance. When the viscosity is too low, easily lead to leakage, reducing the volumetric efficiency of the system, therefore, generally choose suitable viscosity and good viscosity-temperature characteristics of the oil. Further, when the oil flow in the pipeline, there is also along the local pressure loss and the pressure loss, so the design of the pipe line as short as possible, while reducing elbow.
