Differences and characteristics of vertical and horizontal industrial china boiler suppliess industrial boilers? With respect to the vertical boiler, many customers are more inclined to horizontal boiler, and why? In large part because all that space boiler room. Another reason is the customer's misunderstanding that is long sideways horizontal boiler, is standing vertical boiler, for example, many customers believe that large-scale bulk fluidized bed boiler is vertical, but for this boiler, the and no vertical or horizontal points. Boiler industry-specific vertical and horizontal boiler boiler two words, speaking from the model, such as gas-fired boiler fuel WNS is horizontal, that is, "W" of the content, which is a horizontal furnace oil and gas products; standing the boiler is LSG vertical "L" of pressure boilers.
Low nitrogen gas china boiler supplies transformation of environmental significance where the transformation of low nitrogen gas boiler environmental significance where, although natural gas is clean energy, but the combustion process will produce nitrogen oxides, is one of ingredients to form haze. According to the city Thirteen Five energy planning period, from 2014 to 2020, natural gas consumption grew by 14.6 billion cubic meters to 20 billion cubic meters. If you do not take low-nitrogen transformation, the combustion of natural gas will be the main source of nitrogen oxide pollution. After the combustion gas temperature exceeds 1400 ℃, it will generate a lot of nitrogen oxides. Thinking boiler low nitrogen transformation, which is to reduce the combustion temperature to suppress the generation of nitrogen oxides. Chaoyang District Beijing EPB said responsible person, after the transformation, the furnace temperature was controlled at below 1000 ℃, supplemented by staged combustion, flue gas recirculation techniques, such that the concentration of nitrogen oxides is greatly reduced. In recent years, the state vigorously promote clean air plan, Yajian coal. Whether the use of coal-fired central heating boilers, and rural small coal stove for cooking and heating, have changed after another coal to gas in coal, that is, the use of electricity, natural gas and other clean energy alternatives. Thus, in recent years, sulfur dioxide, dust content in the atmosphere continues to decline. But it is worth noting that more and more use of natural gas, also caused a certain amount of nitrogen oxide pollution.
When fully completed by the end of 2017 urban 10 tons of steam / 10-20 tons of steam china boiler supplies regulation task and gas pipeline network coverage of the coal / coal-fired boiler renovation work, fully completed before the end of 2018, 20 tons of steam urban / when more than 35 tons of steam / h coal-fired boilers and renovation work. Before the end of 2017, high-pollution fuel combustion zone ban all types of urban areas in high-pollution fuel boiler to stop using all, or switching to natural gas, liquefied petroleum gas, electricity and other clean energy.
To help businesses to reduce costs to switch to clean energy, the program presents a series of supporting policies and measures, establish clear criteria subsidies, subsidies for the 2017,2018 two years time.
Fuel gas control step and the blowing process air volume of the total fuel gas steam china boiler supplies steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.
