Furthermore, the surface of the superheater is of a tube box type module structure, and the heating surface of the superheater is a light tube; the superheater is connected with the drum through a steam guide pipe.

Furthermore, the surfaces of the five evaporators are all of a tube box type module structure, and the heating surfaces of the five evaporators are all light tubes; and an ascending pipe and a descending pipe are respectively connected between the evaporator and the boiler barrel.

Furthermore, the surfaces of the two coal economizers are both box-pipe type module structures, and the heating surfaces of the two coal economizers are both light pipes; all the coal economizers are connected with the drum through the ascending pipes.

Furthermore, the boiler wall is a light guard plate, and an aluminum silicate fiberboard is filled in the boiler wall.

Compared with the prior art, the utility model has the following beneficial effects:

1. the utility model adopts the design scheme of three flues, the whole flue is in an inverted U shape, and the vertical assembly saves the floor area; and each component device in the boiler can be uniformly arranged in the flue, and each component device can exert the respective function to the best effect because the heating surface of each component is uniform.

2. In the design scheme of the utility model, as the superheater, the evaporator and the economizer are all of tube box module structures, the modular installation and disassembly can be carried out in the flue, so that the installation and the disassembly are convenient; and the heating surfaces of the tube box module structure are all light tubes with reasonable pitches, so that the problem that the flue is blocked due to the fact that dust in the waste heat flue gas of the glass kiln is adhered to the heating surfaces can be solved.

3. In the design scheme of the utility model, the boiler walls are all light guard plate walls, the aluminum silicate fiber boards are filled in the light guard plates for heat preservation, the integral sealing effect of the boiler is good, and the heat efficiency is high.
