1. Circulating fluidized bed boiler is of low temperature combustion, therefore, nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurized during combustion process. Circulating fluidized bed boiler with high desulfuriation rate is economical.
2. Circulating fluidized bed boiler could adopt various coal types and has high combustion efficiency, which is especially suitable for low quality, low calorific value coal.
3. The ash of circulating fluidized bed boiler is of high activity, thus it s easy to realized comprehensive utilization without secondary pollution.
Load distribution of industrial electric dealer boiler machine 20 ton electric boilers are generally single use, right? I believe you should be able to see a lot of household electric boiler is a use, so we do not take consider electric boiler load distribution, but in the electric boiler industry is not the case, let me go find out it. In most cases, the workshop will have more than one electric boiler plant and put into use, due to different electric boiler performance, will involve maintaining unchanged the total load, how the economy and simple distribution electric boiler load problem between, it should specifically how to operate it for the proper allocation among multiple electric boiler in line, it should be two main aspects:? 1, decide which of the normal operation of the electric furnace participate in the total load prescribed. 2, between the boiler load distribution to participate in running the economy how to achieve maximum efficiency. To solve the first problem for model electric boiler and many-faceted work characteristics, troubleshooting boilers, boiler backup and load curve, allowing the boiler manufacturer's technical staff involved in the decision. Premise to solve the second problem is the fuel consumption to a minimum to obtain a predetermined amount of evaporation qualified steam parameters. And correct allocation method there are three, a first distribution ratio of the rated evaporation steam boiler unit; a second principle assigned the highest total efficiency of the steam boiler unit; third fuel consumption according to the principle of equal Incremental to allocate. The above three methods also allow manufacturers of electric boiler auxiliary professionals. So if you need to run a variety of electric boilers buyers, be sure to choose a perfect after-sale manufacturer, if there is heating design capacity of manufacturers would be better, after all, a professional heating design solutions can help you more reasonable the use of electric boiler.

The main areas of use: place heating, bathroom, nursery, electroplating, chemical without high temperature (higher than 100 deg.] C) of. However, once the system layout is unreasonable, without the openings communicating with the atmosphere communicating pipe or valve blockage or installed, it will cause pressure hot water boiler, having a certain degree of risk. 5, pressure boiler water quality: Water pressure boiler required to follow "industrial boiler water quality standards," the specific requirements in the following table: 7, the boiler operating temperature and pressure: The "small hot water boiler and pressure monitoring Safety Regulations" regulations, the atmospheric outlet of the water heater temperature should not exceed 85 ℃, the return water temperature of 60 ℃. Low pressure type water temperature can not exceed to 95 ℃, return water temperature is 70 ℃? Because in security considerations, to prevent heating of the hot water temperature is too high so as gasification, the system will affect the circulating pump running, the system pressure rise; and if failure or insensitive because the thermometer is not allowed to set the temperature are likely to cause system overpressure thus a security risk. Pressure hot water boiler thermometer scale used rated water temperature of 1.5 to 2 times the rated water temperature and the temperature difference between nominal water temperature not more than 20 ℃.
Recently, Changzhi City, Shanxi Province have continued to improve as strongly promote the city's ambient air quality, issued the "Changzhi City, 2018--2019 autumn and winter tackling air pollution comprehensive management action plan" (hereinafter referred to as the "Program"), to take specific measures to 10 31 categories of air pollution comprehensive management.
"Plan" put forward, we will accelerate the adjustment of energy structure in the consolidation of ambient air quality improved results, adhere to progress while maintaining stability, promoting the city's air quality continues to improve.
2020 in accordance with the basic completion of the plains heating pre-season and winter heating coal-life alternative tasks required to develop a three-year implementation program to determine the annual coal task of governance. Husband and actively promote the use of solar energy centralized biomass priority to promoting the bulk coal governance of the main city and the plains surrounding county, the gas will adhere to the reform, in order to set the electrical change, has started in 2017 to protect the "coal to gas "" coal to electricity "project on the basis of reasonably determine this year's" coal to gas "," the number of coal to electricity "project. When the substitution of gas for coal, electricity instead of coal and other alternative methods, the gas source, the power to implement, the existing heating facilities can not be removed.
1, increase efforts to eliminate small coal-fired boilers and furnaces tea, operating farmhouse, drying equipment and other reserves of coal-fired facilities (collectively referred to as coal-fired boilers); and speed up the construction of centralized heating official website, giving priority to the use of combined heat and power production units and other clean heating in the heating mode out of the coverage of the official website of coal-fired boilers.
2, actively promote the 65 steam tons / hour or more coal-fired boilers built-up areas and urban transformation of raw material ultra-low emission boilers, coal-fired plants to achieve ultra-low emissions levels. Biomass boilers should be dedicated boiler, ban coal blended with other fuels, be equipped with efficient dust bags and other facilities.
3, accelerate the transformation of low nitrogen gas boiler NOx emission after the transformation in principle not exceed 50 mg / cubic meter, to encourage the implementation of 30 mg / cubic meter of lower standards.
1, a comprehensive investigation of the use of industrial furnaces, iron and steel, nonferrous metals, building materials, coking, chemical industry, focusing on the smelting furnace, melting furnace, sintering machine (oven), baked (calcined) burning furnace, heating furnace, drying furnace class 9 kinds furnace (kiln), coke oven, gas furnace or the like, to carry out an intensive investigation. And build on November 10, 2018 detailed inventory management, after 15 November 2018 are not included in the list of industrial furnaces management, fully integrated into the autumn and winter peak load shifting production program, implementation of the cut.
2, accelerate the clean fuel substitute, coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and accelerate the use of clean energy and the use of plant waste heat, thermal power plants and the like instead.
