Product description
This product can be widely used in the boiler smoke air system of
various auxiliary reliable isolation.Such as blower, primary fan,
booster fan, coal mill and induced fan, etc., can be isolated in
the boiler operation state maintenance.In addition, at present,
most of the wind doors used in power plants are flap door
structures.Due to the characteristics of the structure itself, the
wind door is not closed tightly and hot air leakage occurs, which
seriously affects the progress of major repair and minor repair of
the power plant, causing unnecessary casualties and economic
losses.In view of this situation, our factory has successfully
reformed and replaced the original flap door of many power plants
all over the country, and has received good economic and social
benefits.
