White smoke coming from the chimney

2011-01-13View Original

Why does a chimney emit a large amount of white smoke in winter? Where does it come from? Does it affect the heating of the coke oven?

Basically normal; it’s cold and the water vapor condenses

White smoke is also a type of smoke that often comes from chimneys. The white smoke coming out of the chimney is actually a type of “vapor”. When exhaust gas is released from a chimney and its diffusion rate is slower than the condensation rate of water vapor in the exhaust gas, white smoke is formed. The main reasons for white smoke coming from chimneys are as follows. 1. Water accumulates in the flue, and it is carried away by the hot exhaust gases, increasing the moisture content in those gases. II. Steam leaks into the gas preheater and enters the gas system. III. Poor drainage of the condensate pipes in the gas pipeline leads to gas containing water. IV. When the temperature drops suddenly, the water vapor in the exhaust gas is rapidly condensed. V. The temperature of the regasified gas itself is too high. VI. Due to a switch failure, the chain failed as it had not been reversed for an extended period of time. For these reasons, it is necessary to ensure proper flood control and drainage for the flue ducts, carry out regular inspections of the water seals for gas condensate, inspect the preheaters, and conduct routine checks on the exchange equipment. :lol

Was it discovered only this year? Is it still like this every year? If it was just discovered, then it’s necessary to check the flue for any problems, such as water accumulation.
