6000 kg natural gas boiler
Four combustion modes of 6000 kg boilerBoiler as an energy conversion equipment, plays a very important role in industrial production, can be said to be the core main force of production enterprises. I know the boiler, but it is estimated that most people do not know much about the combustion mode of the boiler. Today, our Fangkuai Boiler will take you to understand the four combustion modes of the boiler. It can be divided into suspended combustion, boiling combustion, layered combustion and gasification combustion. The following is one by one. First, suspension combustion, also known as fire chamber combustion, is a combustion mode in which fuel is injected into the furnace with air in the form of fog, powder or gas. Suspension combustion ignition is rapid, combustion heat The efficiency is high. It is easy to realize automatic operation. The adaptability to load variation is strong. And the adaptability to the fuel is also strong. However, this combustion mode requires a high level of operation, and should not run intermittently. Secondly, boiling combustion is a kind of fluidized boiling combustion of fuel in fluidized bed under the action of appropriate velocity of air. Boiling combustion is suitable for all kinds of coal, especially inferior coal, such as coal gangue. Stone coal, and so on, this combustion mode on the size of coal particles also have certain requirements. The coal mass must be processed and broken into particles with an average diameter less than 10mm during combustion. Delivered by coal-feeding equipment Enter the furnace. Third, layered combustion, also known as fire bed combustion, is a way of burning fuel in a certain thickness on the grate. This combustion mode is only suitable for solid fuels. However, there are certain requirements for particle size (6~50mm). Layered combustion can basically adapt to solid fuel. As long as the mixture of air and fuel layer is good, and there is a certain combustion temperature, the ideal combustion can be achieved. If the air and fuel layer do not mix well, or the local air supply is insufficient, the combustion will be incomplete and the combustion efficiency will be low. This type of combustion is generally used in chain furnaces. IV. Gasification combustion Gasification combustion mainly refers to gasification and direct combustion of coal put into furnace, and this combustion mode is not suitable for coal with low ash content. High-temperature gasification and staged combustion is different from ordinary gasification combustion. Its utilization principle is as follows: under the condition of oxygen, the fuel surface is heated with high-temperature heat source above 800 ℃, so that the fuel can be rapidly pyrolysis and gasification combustion from outside to inside. Part of the high temperature produced by combustion is then gasified at high temperature, and part of the fuel is discharged for work, thus forming a continuous high temperature gasification combustion reaction.
Check the gas 6000 kg boiler fuel oil boiler before ignition gas development to today, can be described as advanced technology, but in order to safe fuel gas-fired boiler must be assured, fuel gas-fired boiler before ignition still have to check, and I'll tell below we pre-ignition of fuel gas boiler should pay attention to those aspects: first: fuel gas-fired boiler fuel can be gas, fuel oil if it is, will have to check whether normal pump and filter into the oil; if it is a gas, will have to check the gas pressure is normal , should not be too high or too low. Then open the supply valve of the second oil or gas: a gas oil-fired boiler smoke flue valve, it must look is smooth, not clear if there is a security risk must be excluded. Third: to look at fuel gas-fired boiler control cabinet knob is not in the normal position. Fourth: I have a good job cleaning fuel gas-fired boiler. For our own lives and property in the operation of a gas fired boiler think we must strictly abide by its code of practice for safe operation.
Henan 6000 kg 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.
The Fangkuai Group's unique full-operating 6000 kg boiler operation laboratory has an annual operating cost of more than 5 million yuan, which can simulate the operating conditions of various types of boilers under multi-operating environment conditions. The laboratory provides technical tests such as test and inspection, analysis and evaluation, data evaluation, energy saving and environmental protection, and special software from materials to complete equipment, hardware to software, and even complex large systems.
