Hot Oil Natural Gas Fire Tube Boiler

Hot Oil Natural Gas Fire Tube Boiler

Four coal-fired hot oil fire tube boilers precautions to meet a variety of fossil fuels and natural gas sectors of production, often require boiler, the general common is to transform into a coal-fired furnace gas-fired boiler, to change the high fuel costs of coal on the environment cause serious pollution problems, specific issues unique boiler is not a small project, you need to pay attention to a good close links with each transformation in order to avoid failure of transformation, on boiler should be noted that we have to understand the following description. 1, the original boiler demolition work; boiler before carrying out the original host and auxiliary boilers need to be demolished, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work with but also to prevent the demolition process in the event of any accident; 2, note that pressure capacity of the boiler; small boiler into the gas by the coal-fired, also changed the original negative and positive pressure combustion burner, the process you need to pay special attention throughout the furnace wall the structure and sealing, the sealing function, it might cause the boiler after the transformation could not withstand the pressure and accidents; 3, furnace renovation precautions; when in many cases will change the gas burner, because the fuel mist of poor or incomplete combustion of the fuel gas remaining in the furnace a little mistake will cause fire or explosion, it is carried out after completion of the transformation for an explosion vent installed in an appropriate position to prevent the explosion, while additional ignition flame protection means after the boiler guarantee safe operation; 4, after the transformation of the test; after the completion of high-quality boiler transformation, but also the need for reuse Sophisticated testing to confirm their safety, commonly used test method is boiler pressure after the transformation of high-pressure test, and finally pass a test meet the standard may be considered completed after the entire transformation boilers. Caution visible through major transformation over the course of gas boilers, boiler reconstruction requires not only technical but also need to meet the relevant standards in order to ensure more successful boiler and can be smoothly carried out using, of course, in the transformation of the former users need to analyze the structure of the entire boiler study, confirming boiler renovation project can be re-introduced in order to avoid unnecessary waste.

Henan hot oil fire tube 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.
