Problem of using steam to purge the furnace when the heating furnace is turned off
Thread Content
The furnace went out for various reasons; it is necessary to first purge the furnace chamber with steam before restarting it. However, there is a problem: the temperature of the steam is much lower than that of the furnace chamber. Is it necessary to wait until the temperature of the furnace chamber drops? Will it cause damage to the furnace?
Steam purging is primarily intended to prevent water from remaining in the steam pipelines. Before performing purging, it is necessary to drain any water from the pipelines and thoroughly warm them up. With a high furnace temperature, steam will not condense, so there is no damage to the furnace as a result. However, it is still important to control the duration of purging and to ensure that the furnace’s cooling rate does not exceed the specified limits
There will be some to some extent; as long as it’s not too frequent, there won’t be many problems
