efficiency of gas fired boiler

efficiency of gas fired boiler

Gas efficiency of fired boilers and coal-fired boiler, what is the main difference: coal-fired boilers and gas boilers are more types of boilers currently on the market use accounting, many users in the choice of boiler equipment, I do not know which type of selection is better. Today, fast boiler come to you summed up the difference between the three main gas boiler with coal-fired boilers. 1, different exhaust fuel fired boilers using coal, will produce soot after combustion, ash, sulfur grading smoke more, these fumes are causing serious environmental pollution. Gas boiler using natural gas as a fuel, because of its high stability, but no smoke after combustion is discharged, because the gas can be substantially complete combustion of harmful substances ,, which is very small, so there is little pollution to the environment. 2, different heat loss in order to allow coal-fired boilers to maintain sufficient combustion efforts require the use of human or other device to stop adding coal-fired furnace, when the need intermittent operation, it takes a long time to start to increase again furnace temperature, it will generate a lot of heat when the pressure of the fire damage, while the gas boiler is very easy to start and stop, fast heating intermittent operation, thereby reducing heat loss in this process. 3, different treatment after burning coal in the boiler will produce large amounts of ash after combustion, in order to better maintain the quality of the environment, the need to transport the ash to slag professional field for processing. Gas-fired boiler using natural gas this matter, there will be no residual ash after combustion, there is no need to process it, not only to avoid environmental pollution also reduces the labor intensity and the amount of urban ash storage and transportation companies.

Chemical prevent high temperature corrosion of efficiency of fired boiler waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.

Henan efficiency of fired boiler 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.

Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the efficiency of fired boiler is supplied special sea oil processing technology company Shunde indispensable less equipment.
