Four coal-fired fire tube boiler in a turbines 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.
Boiler installation of "blast doors," What is the role now on the market most of the fire tube boiler in a turbines to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.
Which Xining industrial fire tube boiler in a turbines looking for: Xining industrial boiler find Which? There are a lot of companies need to produce industrial boilers in Xining area, industrial boilers had previously been dominated by coal, but now the purchase of multi-boiler is gas-based. This is also in line with the requirements of the current environmental policy. For the procurement of industrial boiler business, then Xining region, for businesses can be compared within the boiler manufacturers nationwide. The company Xining After initial screening decision Xianxiang fast boiler manufacturers for consultation. In this regard, fast boiler manufacturers for the accounting data for the current production status of the enterprise Xining, concluded that the plant with 1 table 6 tons of industrial gas steam boiler on it. Initially, the company for the transport of Xining boiler still have concerns, however, listened to a detailed introduction side boiler fast personnel of the relevant technology. Completely dispel concerns. At present, the price of the model of industrial steam boiler at around 720,000. Recently, the Xining to fast Boiler companies will conduct field investigation, will talk about specific issues related to time after purchase. Domestic large industrial boiler plant which
October 23, the 13th China International Wine & Beverage Processing Technology and Equipment Exhibition (referred to CBB2018) kicked off in Shanghai. Fang Group combine fast wine, the actual needs of users in the field of beverage industry, using its own investment to build more efficient fire tube boiler in a turbine test center platform, continuous investment test and adjust them, to bring the latest "Core Europe" series boilers and condensate recovery system solutions exhibition debut.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.Learn More
Fire Tube Boiler: In a fire tube boiler, hot gas passes through the pipes and boiler feed water is inside the shell to be converted into steam. Fire tube boilers are usually used for relatively small steam capacities with low to moderate steam pressures.Learn More
