Abstract
A novel high-efficiency blower boiler combustor lining of the utility model mainly relates to a gas combustor boiler lining, particularly the blower boiler combustor lining in the field of synthetic ammonia of chemical industry, which comprises a boiler top structure, a hearth structure and a boiler bottom structure. The utility model is characterized in that a boiler top lining is poured in lattices by the steel fiber pouring material; a hearth lining is divided into three layers which comprises a refractory layer, a heat shielding layer and a heat insulating layer form interior to exterior. The heat efficiency of the blower boiler combustor lining using the structure is greatly raised, besides, the utility model has the advantages of convenient construction, a short construction period, low investment, simple operation method, reduced labor intensity and shortened construction period.
Description
Technical field
The new and effective gas blowing boiler of the utility model combustion chamber liner relates generally to gas combustion chamber boiler liner, especially gas blowing boiler combustion chamber, chemical industry synthetic ammonia field liner.
Background technology
Gas making discharging waste gas---the recovery key equipment gas blowing boiler combustion chamber of blowing-out gas in the present Ammonia Production flow process, its traditional inner lining structure is: interior fire-resistant outer insulation, be to adopt refractory brick or castable refractory in the combustion chamber, thickness reaches 230---350mm, the combustion chamber cylindrical shell adopts the diatomite insulation construction outward, and thickness is about 300mm, referring to shown in Figure 1, heat-insulation layer 8 is attached to the outside of furnace wall 4, the flame retardant coating 6,7 that the inside of furnace wall 4 has refractory brick to make.This inner lining structure exists following shortcoming:
1, gas enters with tangent line, and liner is washed away greatly, and fragile refractory material causes leaking out, scurrying fire;
2, use the heavy special form brick to do the ball topping material, weight is big, and the production and processing difficulty is big, is difficult to guarantee construction quality;
3, because poor insulation property needs very thick outer insulation, not only increase investment but also increased the cylindrical shell wall temperature, shortened the cylindrical shell life-span;
4, cylindrical shell wall temperature height, equipment is fragile, and maintenance capacity is big, the parking rate height;
5, the body of heater deadweight is bigger, makes troubles for civil Engineering Design, construction, has increased the design and construction difficulty.
Summary of the invention
The purpose of this invention is to provide a kind of new and effective gas blowing boiler combustion chamber liner, it has overcome the defective of above-mentioned existing gas blowing boiler combustion chamber inner lining structure, and reached the thermal efficiency and significantly improved, and the purpose that easy construction, duration are short, investment is low.
The technical solution of the utility model is a kind of gas blowing boiler combustion chamber liner, comprises top construction and chamber structure, bottom construction, it is characterized in that the furnace roof liner adopts the cast of steel fiber castable lattice; The burner hearth liner is divided into three layers, is respectively flame retardant coating, thermal insulation layer, heat-insulation layer from inside to outside.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, described flame retardant coating is the heavy alumina firebrick, and thermal insulation layer is the lightweight alumina firebrick, and heat-insulation layer is the aluminosilicate refractory fiber brick.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, the thickness of described furnace roof steel fiber castable is 400mm.
Above-mentioned new and effective gas blowing boiler combustion chamber liner, be that furnace bottom is back taper at the bottom of; Tapered bottom surface is the thick steel fibre castable refractory of 400mm, all the other space filling normal concretes.
Above-mentioned new and effective gas blowing boiler combustion chamber liner leaves the liner dilatation joint at furnace roof and burner hearth junction.
Adopt the gas blowing boiler combustion chamber liner thermal efficiency of said structure significantly to improve, and easy construction, the duration is short, investment is low; Its method is simple to operate, and labour intensity reduces greatly, and the duration shortens greatly.
