exhaust of steam boiler properties

Do you know the scale does harm to the heating boiler?After a long period of operation, scale and corrosion will inevitably occur in heating boilers, which is one of the main causes of boiler accidents. My company as a professional boiler manufacturers, in order to arouse the attention of the vast number of users to boiler scale, The following professional staff of the boiler manufacturers introduce to you the harmfulness of boiler scale and waste a large amount of fuel because the thermal conductivity of the scale is only a fraction of that of steel, so the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire so as to cause the heat loss caused by outward radiation and exhaust smoke. Due to the different working pressure of the boiler, the scale class The quantity of fuel wasted is different with different thickness and thickness. According to the test and calculation, the loss of fuel increases with the increase of scale thickness. It is easy to make steel plate and pipe burned because of overheating. After boiler scaling, it is necessary to keep certain working pressure and evaporation, so the temperature of fire side can only be raised, but the thicker the scale, the lower the coefficient of thermal conductivity, the higher the temperature of fire side. Generally speaking, the temperature of boiler fire side is about 900 ℃, and the temperature of water side is about 190 ℃. When there is no scale, the temperature of the steel plate is about 230 ℃, and once the scale is about 1mm, the temperature of the steel plate is increased by 140 ℃ compared with that without scaling. Left and right. When the metal reaches a certain temperature, the plasticity index of the metal begins to decrease, and the metal will creep and deform because of the overheating when the temperature is higher. So boiler scaling is easy to burn the metal. The accidents caused by scale in boiler account for about 1/3 of the total boiler accidents due to increasing maintenance costs and decreasing service life. Boiler accidents not only cause damage to equipment but also threaten personal safety.

Power Plant Boiler

Thermal power generation is the main way of generating power in China, power plant boiler as one of the three main equipment in power plant, developing with the development of China's thermal power industry.

How to ensure a smooth vertical exhaust of steam boiler properties installation? Vertical steam boiler can efficiently generate heat and steam to provide a good impetus for manufacturers. However, due to pressure equipment boiler it is a kind of operational risk, so not only want to buy high quality and reliable to use vertical steam boiler, but also pay special attention at the time of installation. Following on from the vertical steam boiler manufacturers to tell you about how to ensure a smooth installation of boiler success. 1, select the optimum location in order to ensure the smooth vertical steam boiler installation before installing good first determine the most suitable installation site, in order to ensure that the pipeline can reduce heat loss caused by heat dissipation. Therefore, the choice of location is best to close coherent location with easy drainage, fuel and ash storage and easy transportation. In addition, the boiler room layout also comply with the relevant countries. 2, boiler foundation to prepare construction plans need to be developed in the installation of vertical steam boiler in advance, and the use of appropriate materials to make a slag pit foundation work, in addition to leaving a good pre-filter and a lead anchor bolt hole of the fan, the installation of It also needs strict accordance with the construction drawings foundation for execution. 3, do on-site management company not only to choose a qualified installation company to install vertical steam boiler, but also do on-site installation management, including the verification of the installation's qualification certificate, staffing, construction orchestration conditions. And also to get in touch with the responsible local boiler supervisory authority, as required for the installation of the boiler unit boiler unit holders of certificates issued by the competent authorities in line with the boiler unit range. Further, the vertical steam boiler to have someone involved in negative process, comprising: a fireman, foreman, fitter, rigger, cold work, and welders and other auxiliary work. If you can do all three areas so we can guarantee the smooth vertical steam boiler installation. Since the installation of the boiler Importance of Being Earnest, so in this country also has a corresponding control, while enterprises in order to later boiler operation safer and more reliable, you need to pay attention to selecting well-known vertical steam boiler installation company to ensure the reduction of losses and guaranteed to run Safety.
