high efficiency natural gas fired hot water boiler prices
Brief characteristics of coal-fired boilers 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.
The difference between low nitrogen gas boiler with ordinary coal-fired boiler from China after the latest air pollution emission standards introduced across the country have carried out air pollution control projects, ordinary coal-fired boilers due to serious pollution faced elimination and replacement process. Low nitrogen gas boiler because of its unique low nitrogen, clean, environmental advantages, namely a push into the market has been widely welcomed. Today, fast boiler come to you talk about the difference between natural gas boilers with low nitrogen ordinary coal-fired boilers. 1, differences in emissions due to the use of ordinary coal-fired boiler fueled by coal, according to the composition of coal, which determine the more discharged flue gas after the combustion of soot, ash, sulfides, flows into the atmosphere can result in serious pollution influences. A low nitrogen gas boiler using natural gas as fuel, almost no soot and other harmful substances combustion; low nitrogen after processing, harmful substances is reduced to a negligible extent. 2, ordinary coal-fired boiler combustion technology differences are mostly fed directly into the furnace of coal combustion, incomplete combustion of coal will be an inconvenience. Low nitrogen gas combustion boiler made a change in the natural gas and oxidant gas (air) are mixed in a certain proportion of advance before entering the furnace, so that the gas will be more fully combustion, fuel efficiency is also improved. 3, differences in the safety factor by coal-fired boiler explosion occurred in recent years across the country, we can see that a lot of coal-fired boilers there are still security problems, once the risk of an accident, whether it is physical security or economic interests will suffer great losses ,The consequences could be disastrous. A low nitrogen gas boiler for safe disposal can be seen in the following points. First, fuel storage and delivery are established directly connected to the pipeline, and the pipeline have done more treatment, both the quality and safety factors have been improved. Secondly, the current low nitrogen gas boiler mostly have joined the intelligent automatic control system; it just as fast boiler, each boiler is equipped with independent research and development of intelligent control system, with matching boiler is very high, people fireman only need to follow the instructions HD display menu operation, start to finish, adjust a variety of state (water supply, output ...), outage, etc., and easy to operate but also to avoid direct contact with the staff of the boiler. In addition, low nitrogen gas boiler with a comprehensive probe detection device, connected enterprise cloud services remote monitoring system, water level, pressure, temperature and other abnormal occurrence which step will be detected immediately and begin warning to remind people immediately see the boiler status fireman . Continuous technological innovation, is providing energy saving, high-quality boiler equipment lies. Low nitrogen gas boiler after many trials and engineering applications, and achieved great results; at present, has been widely used in many industries, not only protects the environment, energy conservation, but also to control the pollution, the technology is particularly worth the continued research and development applications.
It is reported that fast boiler opportunity to help APEC summit, with more than Institute, universities collaborate to jointly develop the latest ultra-low nitrogen oxide emissions control technology, nitrogen oxide emissions will be maintained at 33 mg / m within the scope of the emissions has exceeded European standards in the future, this technology will better serve the Beijing as well as the national gas boiler renovation project. "Our vision is to: continue to meet the energy needs of user convenience and energy saving, the fast boiler build the first brand of Chinese clean boiler future we will continue in different areas of ultra-low nitrogen, ultra-low dust, low noise, etc. continue to explore. in order to achieve greater results. "the technician said in conclusion.
How to make boilers more energy-efficient? (Common measures) 1. boiler design of energy-saving measures (1) boiler design, first of all should be a reasonable selection of equipment. In order to ensure safety and energy conservation in the industrial boilers meet user requirements, should be due to self-select the appropriate boiler design boiler type in accordance with scientific and rational selection principles. (2) when the boiler selection, but also the right choice should be based on the type of boiler fuel boiler, industry, geographical install a reasonable choice of fuel type. Reasonable blending the coal moisture, ash, volatile matter, particle size and other combustion equipment meet the requirements of the importing boiler. At the same time, we encourage the use of new energy sources such as straw briquettes as an alternative fuel or blended fuels. (3) In selecting fans and pumps, to select a new type of energy-efficient products, can not choose backward out of the product; boiler operating conditions by matching pumps, fans and motors, to avoid the phenomenon of the "big horse car", the current inefficient use, a large auxiliary energy consumption, should be modified or replaced with energy-efficient products. (4) a reasonable choice of parameters boilers generally at efficiency of 80% to 90% of the maximum rated load, as the load decreased, the efficiency also decreased. Capacity boilers generally used with greater than 10% of the actual vapor on the line, such as when the selected parameters are not exactly according to the standard series, the boiler can choose a higher gear parameters. Auxiliary boiler selection also refer to the above principles, to avoid the "big horse cart." (5) reasonably determine the number of boiler principle is to be considered normal boiler maintenance shutdown, and pay attention to the number of boiler boiler room, no more than 3 to 4 units. (6) a boiler economizer SCIENCES designed to reduce heat losses and improve the thermal efficiency of the boiler, economizer heating surface disposed in the boiler backpass, boiler feed water is heated by heat of the flue gas, to save energy, the installation Xingmei after, a feedwater temperature increase the temperature difference between the boiler water and feed water is reduced, reducing the thermal efficiency of the boiler feed water is generated. Countries: where <4 t / boiler flue gas temperature is not greater than 250 ℃; ≥4 tons / boiler flue gas temperature is not greater than 200 ℃; ≥10 tons / boiler exhaust gas temperature is not greater than 160 ℃, province or should be installed coal is.
