papermaking natural gas hot water fire tube boiler supplier

To people a good living environment, the Sichuan Provincial Government to respond positively to the national environmental policy, released the latest notice "Sichuan Province to win the Battle of Blue Sky" and other embodiments of nine. Which highlighted: increase Condensing units and cogeneration units technological transformation efforts, speed up the heating pipe grid design. In areas do not have central heating conditions, the existing multiple small coal-fired papermaking hot water fire tube boiler suppliers, to replace the principle of construction of large-capacity coal-fired boilers in accordance with the same amount. For shutting down key areas of environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance.

Scientific and orderly promote clean energy development and utilization of hydropower, natural gas (shale gas), wind power, solar, biomass and so on. As of 2020, the province's hydropower installed capacity reached 79 million kilowatts, the proportion of non-fossil energy consumption reached 37.81%, increase the proportion of natural gas consumption to 16.19%.

The implementation of "Sichuan" Thirteen Five "energy development plan" requirements on coal consumption, increase the intensity of coal washing, coal simultaneous construction of new coal washing facilities, supporting the completion of existing coal mines coal washing facilities in accordance with points Area. Improve coal quality and use of industry standards, do not comply with the provisions of commercial coal quality management and environmental protection requirements of the indicators listed commercial coal. Prohibit the circulation and use of low-grade bulk coal, bulk coal investigated and dealt with according to the law without a license behavior. Increase the civil bulk coal clean governance efforts to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves, strengthen civil bulk coal management. Strengthen regulation and control coal use in autumn and winter. For shutting down key areas of environmental protection, energy, security and other non-compliance of more than 300,000 kilowatts coal-fired units.

Brief characteristics of coal-fired papermaking hot water fire tube boiler suppliers and gas boilers difference: one is the most common category of boiler coal-fired boiler and gas boiler, although it is more consistent in showing the effectiveness of the integrated, but in the specific combustion, combustion products and there is a huge difference on the specific operating requirements and work processes, the following article will be brief characteristic differences coal-fired boilers and gas boilers for everyone. First, the coal-fired boiler combustion grate firing combustion, coal fired by a plane conveyor chain grate, complete combustion process in the furnace. While the combustion gas boiler combustion chamber, the gas is mixed with air in advance is set in proportion to the burner, injected into the furnace through a nozzle, the torch was installed in the furnace to complete combustion. Second, the automatic control of the force due to coal-fired boilers factors coal, coal seam thickness, the amount of blowing, the wind amount, and the air volume distribution grate speed limit, to be difficult to automatically adjust the operating parameters of the boiler according to the load. And high-quality gas boilers less impact on factors, may only be adjusted according to the size of the fire burner load, easy to achieve automatic control. Third, the combustion products of coal mainly by c, H, 0, N, and other elements composed of ash and water, but not the mechanical mixing of these components, but a very complex compound.

What is the principle of the papermaking hot water fire tube boiler supplier? No matter how much the tonnage, the boiler works basically the same. Role of the boiler fuel chemical energy is converted into thermal energy, heating and heat inside the pot with water to become superheated steam having a mass and a sufficient amount (steam temperature, steam pressure) of the steam turbine for use. Now the power plant boiler capacity, high parameters, technical complexity, high levels of mechanization and automation, the main fuel is coal, and coal prior to combustion of pulverized coal first made, and then into the boiler combustion heat release in the furnace. Broadly speaking, the work process is the main boiler fuel combustion, heat transfer, vaporization and heating of the water with the superheated steam and the like. The entire boiler boiler composed of two parts and auxiliary equipment. Boiler: boiler body is the main part of the boiler equipment, is composed of two parts, "pot" and "furnace" composition. "Pot" is the soda system which main task is to attract the heat receiving fuel discharged, the water is heated, evaporated and finally becomes superheated steam having certain parameters. It consists economizer, the drum, the downcomer, the header, water wall, superheater and reheater connecting pipes and other equipment and valves. 1) economizer. Vertically positioned rear of the boiler flue, the use of flue gas waste heat boiler feed water, reducing the exhaust gas temperature, increase boiler efficiency, fuel economy (2) drum. At the top of the boiler, it is a cylindrical pressure vessel, which is under water, the upper portion of the steam is that it accepts the economizer runoff, while the downcomer composed header, Wall water circulation circuit. Wall water absorbs heat generated in the soda mixture was collected in the drum, conveyed by the saturated steam to the superheater steam-water separator (3) downcomer. Water supply pipe water wall, the effect of which is introduced into the water in the steam drum to the lower header redistribution respective waterwall tubes. Dispersion in small diameter and the large diameter downcomers Downcomer two kinds. Small diameter tubular small diameter drops, the water cycle of negative (4) waterwall lower header. The main role of the header is a mass pooled or working fluid through the header to the header redistributed through other conduits. A water wall is thicker lower header tube closed at both ends, its role is connected to the downcomer and the water-cooled wall, so as to function together, mixing, redistribution effect working medium (5) water wall. At the furnace around its main task is to absorb radiant heat of the oven, to evaporate water, which is the main heating surface modern boilers, while protecting the furnace wall (6) superheater. Its role is to drum saturated steam into superheated steam on heating (7) having a predetermined temperature reheater. Its role is done in the steam turbine power section is heated up again, and then continue to work in the steam turbine. "Furnace" is the combustion system, its task is to make the fuel burn in a good furnace, heat. It consists of the furnace, the burner, ignition means, air preheater, the smoke duct and the furnace wall, frame and other components. (1) furnace. It is transferred from the furnace wall and into the water wall for fuel combustion, the fuel combustion in suspension, the release of large amounts of heat within the space. (2) burners. Located on the furnace walls or corners, its role is the fuel and air injected into the furnace at a constant speed, so that it can be well mixed in a furnace in order to ensure timely ignition and rapid and complete fuel combustion. DC sub-burner and swirl burner two basic types. (3) air preheater. Located in the boiler backpass, whose role is to use waste heat of flue gas to heat the fuel required for the combustion air, exhaust gas temperature can be further reduced not only, but also for strengthening the furnace combustion, improve the economy of combustion, pulverized coal drying and conveying is advantageous of. Boiler efficiency can be increased by 2%. And rotary two kinds of charge. (4) smoke duct. From the furnace wall is a pipe, the pipe heating surface and the portion of the tube wall and other components of the package, for guiding the flow of flue gas through the heat exchanger and the respective heating surface, and is divided into horizontal flue backpass. Auxiliary ventilation apparatus comprises auxiliary equipment (delivery, induced draft fan), a fuel transportation equipment, milling system, in addition to ash and dust removal equipment, desulfurization equipment.
