Horizontal Gas Boiler Cheap Sale

Problems coal horizontal boiler cheap sale gas boiler gas coal problems are: 1, more coal ash, 2, unevenness of coal particles, 3, coal contains a large amount of impurities, 4, a lower heating value of coal, 5 when combustion is not easy to ignite fire, 6, coal moisture content uncertain. 7, does not burn coal, slag high carbon content. In general, use is preferably designed coal boiler design coal or coal close, in order to ensure stable combustion. In recent years due to the growing tension surrounding the coal supply, coal supply has become diversified, coal quality is very different than before coal, have a great impact on the stability of the boiler combustion and normal heating operation. Impact of coal combustion boiler stable for: calorific value of coal is coal reflects an important indicator of good or bad, when the low calorific value of coal to a certain value, will not only affect the incomplete combustion instability and can lead boiler flameout, the outlet temperature of the boiler is difficult to compliance, affecting the normal operation. Volatile combustion and can be deposited at lower temperatures, as the combustion heat, the temperature rapidly increased coke particles, provide an extremely favorable conditions for ignition and combustion, volatiles further increased coke deposition and internal voids and the external reaction area, will help improve the speed of burning coke. Thus, the greater the content of volatile, nonflammable, the less fixed carbon in the coal component, the easier coal burning ember, devolatilization of many voids, increases the surface area of ​​the reaction, the combustion reaction is accelerated. When the volatile content is reduced, pulverized coal ignition temperature significantly increased, the hot increases, difficult fire, ignition time required becomes longer, the combustion stability is reduced, shifting the center of the flame, furnace absorbed radiation heating surface reduce heat, increase the heat absorption of the convection heating surface, the rear exhaust temperature, exhaust loss increases.

Henan horizontal boiler cheap sale manufacturers fuel gas combustion boiler features a contrast, combustion of fuel is a liquid fuel and fuel oil, its boiling point is always lower than the ignition point, so that fuel combustion is always performed in the gaseous state. Fuel oil particles atomized by the jet into the furnace after the furnace is heated by high temperature flue gas, gasification, and hydrocarbon ambient air encounters the oxygen gasification, a flame. Heat produced by combustion of oil particles pass a part of the gasification and combustion of oil particles continuously, until the burning ember. The smaller the diameter of oil particles, the faster the combustion of oil particles. Similarly, the oxygen required for combustion of oil particles can be supplied in time, the combustion of oil particles can more quickly. Therefore enhanced combustion of oil must do the following: 1, to improve quality of atomization, the oil particle diameter is reduced; 2, increasing the relative velocity of the air and oil particles; 3, reasonable air distribution. Second, the combustion gas boiler manufacturers Laid Henan boiler ignition gas with a high calorific value, large amount of air, can make the combustion gas, a large amount of air mixed therewith. No fuel combustion gas atomization process with the gasification process. Gas and air mixing mode, the flame length and flame temperature has a significant impact on the intensity of the combustion. Depending on the mixed mode, the combustion method of the boiler manufacturer Henan gas boiler can be divided into three types: 1, i.e., this method does not pre-mixed combustion diffusion combustion, but interdiffusion gas nozzle opening, and burned. Shao Shao stability advantages, the structure of appliance is simple, but the flame is longer, easy to produce incomplete combustion and carbonization of the heated area. 2, partially premixed combustion air prior to combustion such a way that the combustion of part of the air mixed in advance with the gas (primary air excess coefficient between 0.2-0.8), followed by combustion. The advantage is clear combustion flame, combustion strengthened, high thermal efficiency. However, combustion instability, and high combustible component of the control primary air requirements. The gas burner usually used such combustion. 3, i.e. flameless combustion air which has been uniformly mixed with the combustion gas prior to such gas required for combustion. Primary excess air ratio is equal to the excess air ratio for complete combustion of the fuel required to obtain oxygen from the ambient air during the combustion process. When the combustion gas and air mixture reaches the combustion zone can be completed in an instant.

November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast horizontal boiler cheap sale - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.

Comparison of coal-fired steam horizontal boiler cheap sale and gas steam boiler? Which is more cost-effective? There will be new users are asked coal-fired steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear lead and coal-fired steam boiler, gas steam boiler supporting a dedicated burner, put the cost of just one burner price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than coal-fired steam boilers and more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. Where the coal-fired steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Coal-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that the coal-fired steam boilers now more stringent. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze the cost of fuel: coal-fired steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view on coal in order to save operating costs more than gas steam boiler steam boiler, but coal-fired steam boiler steam boiler environmentally friendly than gas in environmental protection, environmental pollution is now increasing in recent years, so the state to environmental pollution control is relatively strict, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.
