But some valves should check before running the opening and closing flag. The following is a gas boiler manufacturers ajar gas boiler in operation, the valve should open quickly points to note: gas boiler slowly open the valve is first opened, and then open the quick opening valve, the preheating duct, then fully open. In order to better sewage, can be repeatedly turned on and off quickly open the valve. After discharge, to open the valve to close quickly, and then slowly open the valve to close, and finally quick opening valve is opened, the washing water between the two valves.
Category fuel steam boiler steam boiler fuel can be divided by professional electric steam boiler price, steam boiler fuel, gas steam boiler; according to the structure can be divided into vertical and horizontal steam boiler steam boiler, steam boiler small, mostly single and double back to back the vertical structure, large steam boiler horizontal structure of the three-loop. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. The main findings are as follows: 1. Vertical double structure vertical oil return steam boiler burner shutdown mode, two circuit configuration, fuel combustion, boiler stable; flue insert spoiler, smoke slow speed, increasing the heat transfer, high thermal efficiency, reducing user costs. Horizontal Horizontal three loop steam boiler shell is a full moisture pyrotechnic refluxed for three loop pipe structure, large combustion flame in the combustion chamber a slight positive pressure, fully extended, combustion heat load is low, the high heat of combustion efficiency, reduce exhaust gas temperature, energy saving, economical use. Wave structure and the furnace flue pipe threads not only improve the strength of the heat absorption of the boiler, and the heating surface to meet the requirements of expansion, scientific, reasonable, and durable.

"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.
Steam boiler is too many forms, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.Free Chat
