Abstract
The utility model relates to a front smoke box mechanism, in particular to a front smoke box mechanism of a fire tube type waste heat boiler. The front smoke box mechanism comprises a smoke cylinder and a front smoke box body. The front smoke box body is sleeved on the head of the smoke cylinder. A fire-resistant layer is disposed between the outer side wall of the smoke cylinder and the front smoke box body. A thermal insulating layer is disposed between the fire-resistant layer and the front smoke box body. The front smoke box mechanism is simple in structure and good in application effect.
Description
Technical field
The utility model is a kind of front smoke box mechanism, particularly a kind of front smoke box mechanism of fire tube waste heat boiler.
Background technology
Waste heat boiler of the prior art, complex structure, result of use is poor.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, and a kind of front smoke box mechanism of fire tube waste heat boiler simple in structure is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of front smoke box mechanism of fire tube waste heat boiler, comprise chimney cylindrical shell and front smoke box casing, the head of described chimney cylindrical shell is with the front smoke box casing, is provided with flame retardant coating between the lateral wall of described chimney cylindrical shell and front smoke box casing, is provided with thermal insulation layer between described flame retardant coating and front smoke box casing.
As preferably, described thermal insulation layer fixes with chimney cylindrical shell and front smoke box casing respectively by shrouding, and described flame retardant coating and thermal insulation layer fix by the pawl nail.
As preferably, described chimney cylindrical shell and front smoke box casing fix by gusset.
Therefore, the front smoke box mechanism of the fire tube waste heat boiler that the utility model provides, simple in structure, result of use is good.
