Claims

[Scope of utility model registration request]

Regarding a combustion gas drift prevention plate for preventing ash unit lotion in a lime-fired boiler, the position of the drift prevention plate can be adjusted from the outside of the boiler to prevent mechanical damage caused by contact of the heat exchanger tube with the drift prevention plate. A combustion gas drift prevention plate device which maintains the optimal relative position of the heat exchanger tube and the drift prevention plate under operating conditions, and facilitates replacement of the drift prevention plate.
