5000kg Vertical Steam Boiler
Heating boiler with hot water boiler or 5000kg vertical steam boiler is better? Whether hot water boilers or steam boilers are heat output devices, to provide hot water and steam. The minimum tonnage of industrial heating boiler now offers fast boiler is 99KW vertical hot water boiler, the largest is 80 tons SZS type hot water boiler pipes. Whether large or small boiler boiler, pollutant emissions are well below national limits, ensure that customers use the boiler, no environmental worries decades. There is a problem many users heating, heating boiler with hot water boiler steam boiler good or better? Fast boiler to answer your questions, at present, less to do with steam heating boiler heating mode, if the heat source is steam, but also use more heat exchangers do mediation, but also hot water to reach the final users do cooling medium. The plants do, while for the production of steam, the steam does not need to break off, heating of buildings or workshop. Here's a look of steam boiler heating it. 1, the temperature rise is too fast, the radiator cold and hot temperatures, easy to leak; 2, the pressure rise is too fast, the heat sink is likely to cause metal fatigue, reduced life, are likely to cause the radiator burst; 3, the radiator surface temperature is too high , easy to burn the people, but also result in poor weather conditions indoors, house dust exploded above the radiator, resulting in blackening the wall above the sink; 4, if the heating steam heating pipe before sending ineffective, when feeding the steam will cause water hammer, the water in the radiator is formed under the impact of water vapor hammer, impact radiator and pipes, noisy, then affect the rest of the night, but also damage the radiator and pipes; 5, the water heated in the boiler to absorb heat released fuel and the water molecules have to absorb some heat into steam, causing energy waste. In summary, compared to the heating and hot water boiler, steam heating boilers were not economic, risk, which is why in recent years the use of steam boiler when the heat source is less and less. We suggest that you use for heating hot water boilers, more cost-effective.
Boiler maintenance boilers way with the development of society, more and more people use, during use, we can not forget its care and maintenance, which also have a specialized technical maintenance, the following teach everyone boiler routine maintenance: 1, all oil cups are filled with oil. 2, at all events are required to add oil. 3, the bottom of the boiler water is not ground plane, to prevent wet etching of the base. 4. The grate shall tighten or loosen, four bolts on the housing shall relax the base beforehand. 5, when the induced draft fan to severe vibration should stop checks, generally based internal impeller wear or fouling caused by severe and should be replaced. 6, class check grate reducer, the tap head and gear lubricants induced draft fan in the bearing housing is held within the allowable range, light fuel should be promptly, to clean up oil leakage. 7, the gland gasket lower portion of the slag, as grout leakage found, litter should be kept pressed, or replaced with a new temporary parking gasket stop leakage, and check if grout leakage into the bearing, should be open the cleaning. If you want long-term use can improve the efficiency of the boiler and then you need to do routine maintenance and repair, of course, if handled properly there may be accidents happen, you have to be before they can according to the correct method.
Recently, the Weifang Municipal Quality Supervision Bureau investigation work for power plant boilers, boiler pipes mainly the situation, avoid boiler due to pipeline damage caused by explosion or other accident, serious economic losses and social impacts.
Quality Supervision Bureau adhere to problem-oriented, carefully study and strictly enforce the AQSIQ and the Provincial Quality Supervision Bureau of the requirements for the range of power plant boiler pipeline design, manufacture, installation, inspection, management and regular inspection of the use of accurate knowledge boiler safety awareness the importance of strengthening the red line awareness, risk awareness and responsibility to play, continue to maintain high pressure, strengthen safety supervision work of the power plant boiler tubes.
Bureau of Quality Supervision focus on checking whether the boiler tubes carry out regular inspections in the construction of power plant boiler accessories combination whether to implement supervisory inspection of manufacturing, installation work unit level meets standard requirements, flow meter housing if there is a security risk, whether the use of units developed power plant boiler tubes emergency plans and emergency rescue exercises, in a timely manner to improve the problems found.
To date, Weifang City inspectors were deployed 257 times, check the power station boiler unit 58, checking in with a number of boiler 193 units, eliminate safety hazards 78.
Traditionally, the coal ignition temperature in CFB boilers is estimated from experience with little theoretical basis and relatively large uncertainties in the estimates. These uncertainties result in operating difficulties and economic loses. For example, if the coal is fed into a furnace at a temperature lower than, the coal will not burn and the furnace temperature will decrease even more. Once the fuel concentration and temperature in the furnace reach the critical conditions, the mixture will flash and the furnace temperature will suddenly increase which leads to control problems. Feeding the coal in the furnace at temperatures higher than is safer but costs more start up time and fuel. Laboratory scale fluidized beds are often used to measure the coal ignition temperature in CFB boilers, based on the criteria such as the flame and spark characteristics, bed temperature response and oxygen response.The coal ignition temperaturein, in fluidized beds boilers is not only a function of the physical and chemical properties of the coal, but is also influenced by the heating rate, the boiler structure, the fluidization velocity and the particle size as well. Therefore, a set of standard operating conditions was specified for the measurements of the coal ignition temperature,in a laboratory scale fluidized bed boiler. This article described a standard for measuring the coal ignition temperature with typical results in a laboratory scale fluidized bed with under-bed preheat system. The tests measured for seven coal types were compared with the actual feed temperatures, in real CFB boilers in China at various loads. The temperature differences between measured in the laboratory fluidized bed and measured in the real CFB boilers for the various types of coal were plotted against the proximate analysis of the coal to estimate the lowest feed temperature in real CFB boilers.
