The smoke exhaust heating unit not only increases the questions about steamboiler load, but also finds that the smoke exhaust temperature is increased to a certain extent. In operation, it is found that the flue gas temperature of this kind of boiler is lower, the exhaust temperature is only about 120 ℃ at 70% load, and 103 ℃ at 150% overload. Therefore, you can not install economizer. Although the actual exhaust temperature is lower than the standard, there is no corrosion of flue gas to flue gas and fan after operation. In addition to the low exhaust temperature in the overloading operation of the boiler with threaded flue gas tube, the exhaust temperature of other type boilers under reasonable air distribution is lower when the overloading operation is carried out. For example, the exhaust temperature of SZL4.2-95/70 hot water boiler is about 208C ~ 210C at 70% load and 210 ℃ ~ 213C when overloading is 140% or so, for example, the temperature of exhaust gas is about 208C ~ 210C in 70% operation of the hot water boiler with door produced by a certain factory. When the exhaust temperature of some hot water boilers exceeds 150 ℃ due to design reasons and overloading, a economizer should be installed to reduce the exhaust temperature and avoid the fan running beyond the design temperature (200 ℃).
Pressure questions about steamboiler installation if need be reported and how to determine water boiler? This important site for boiler products, I believe we will not feel strange, because it is the site of important and flagship product, so its knowledge and understanding, it is very necessary to actually work in to proper use, and at the same time, you can give yourself more knowledge and understanding, so that you can derive some new knowledge, rather than nothing. 1. The atmospheric boiler in the boiler this kind, its installation requires filing it? For this kind of boiler pressure boiler, which is installed on the need to be reported, it is to see how much the boiler million kilocalories, if, that is 300,000 kcal or less, then, does not require installation of filing If more than 30 million kcal, is needed. However, for the moment, this provision, nor is her unchangeable, in some places or occasions, it can be change.
