Boiler start-up process, the drum, the lower wall temperature difference is how to generate? During start-up, the drum wall absorbs heat from the working fluid, the temperature gradually increased. Start early, steam temperature from boiler water circulation has not been correctly set up, the drum water is not flowing state, convection heat transfer coefficient of the wall of the drum is very small, i.e. very slow heating. An upper drum into contact with saturated steam at elevated process pressure, a portion of the vapor will condense adherent, exothermic condensation of the metal walls of the drum, which convective heat transfer coefficient than the lower aqueous many times higher. When the pressure rises, the upper wall of the drum can be relatively close to the saturation temperature corresponding to the pressure, while the bottom wall is raised very slowly. Thus formed on the drum wall temperature is high, the low temperature condition lower wall. Boiler boost faster, the larger the temperature difference between the lower wall. On the drum, the temperature difference of the lower wall, the upper wall of the drum by the compressive stress, tensile stress by the lower wall. Large temperature difference, the greater the stress, the drum tends to cause severe shape deformation of the extrados. To this end, China's relevant rules of order: the drum, the lower wall allows the temperature difference is 40 ℃, the maximum does not exceed 50 ℃.

Whether there are differences hot water steam temperature from boiler and stove and water tank hot water boilers description of this kind, I believe we are not unfamiliar to it, but should also have a certain degree of knowledge and understanding, so, based on this case, in order to let everyone have a comprehensive understanding of this a boiler, rather than a smattering of knowledge, below, will it explain the relevant knowledge, so that we have the learning content, thus, to achieve the above purpose. 1.6 tons of hot water boilers, which heat production is generally much? Its water production per hour is how much is? 6 tons of hot water boiler, heat production which is typically 1.8 million Kcal / H. If you want the water heated from 15 deg.] C to 100 deg.] C, then, may be derived from 1800000 ÷ 85 = 21176.4706L this equation, the boiler water production per hour is 21 tons of hot water. However, under other conditions and requirements, it may not be this value. 2. The hot water boiler and stove, there is a difference? Hot water boiler, which is a boiler, which is obtained by heating water and hot water and cooling cycles, heating to achieve the purpose and effect, therefore, the heating can be used in the home and enterprises. The stove, which is heated by heating the air to achieve this object, therefore, can be used in plant breeding and cultivation of heating, or the drying. Therefore, it can be seen from their definitions, hot water boilers and stove, there is a significant difference between the two is. 3.4 tons of hot water boilers used in the tank, what specific species that have? 4 tons of hot water boiler, the water tank with which it is, in general, is used by a boiler water pipe network, and for storing oxygen water or demineralized water. And on the tank volume, and should make up the amount of water required to decide. In the specific type of tank, and the tank is softened both oxygen tank. 4. Working pressure hot water boiler, whether it is an important parameter? Working pressure hot water boiler, which is an important parameter, therefore, should pay attention to and take seriously. All of us in terms of its decision on factors, there is a boiler system pressure required, and the system resistance system is highly related to these three. And, at this point, we should have a correct understanding, you can not go wrong.

SATURATED STEAM - THE MARCET BOILER

Steam Heating System Operating Temperature

Because a steam boiler makes heat by producing steam - by boiling water, at sea level, the temperature at the boiler will be boiling or 212 °F or close to that figure. The actual steam boiler temperature may be a bit lower at high elevations above sea level, and the steam boiler temperature will be a bit higher than 212 °F for boilers operating at slightly higher pressures, as we'll illustrate in a table below.
