Abstract
The utility model relates to boiler plant technical field, especially relates to a kind of clean type coal boiler.Be characterized in comprising body of heater, described body of heater is disposed with upper furnace door, lower furnace door and cleanout door from top to bottom, described lower furnace door is set to multiple from top to bottom, is provided with one deck fire grate in each lower furnace door, and body of heater both sides are also provided with air inlet.Its fire grate adopts inverted trapezoidal, and make fire grate upper surface level and smooth, during burning, heating surface area is large, and between tube and tube, interval is little, not easily card slag, sufficient combustion; Spacing before fire grate tube and tube reduces from top to bottom successively, and namely fire grate arrangement is more and more closeer, cinder can be cleared up in layering, avoid easy card slag in prior art, the defect of waste coal.
Description
Technical field
The utility model relates to boiler plant technical field, especially relates to a kind of clean type coal boiler.
Background technology
Along with the development of society, boiler use is industrially increasingly extensive.At present, the boiler used on the market, unreasonable in its structural design.Fire grate is cylindrical tube, and heating surface area is little, forms V-arrangement opening between tube and tube, easy card slag; And fire grate only has one deck, if interval is excessive between tube and tube, then coal easily spills, and forms the wasting of resources, if interval too small, then and easy card slag, not easy to clean.
Summary of the invention
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of clean type coal boiler, thus effectively solves the defect existed in prior art.
For achieving the above object, the technical scheme that the utility model is taked is: described clean type coal boiler, be characterized in comprising body of heater, described body of heater is disposed with upper furnace door, lower furnace door and cleanout door from top to bottom, described lower furnace door is set to multiple from top to bottom, be provided with one deck fire grate in each lower furnace door, body of heater both sides are also provided with air inlet.
Described fire grate is set to inverted trapezoidal pipe and is arranged in order formula structure, and the spacing between the inverted trapezoidal pipe in every layer of fire grate reduces successively from upper strata to lower floor.
The beneficial effects of the utility model are: described clean type coal boiler, and its fire grate adopts inverted trapezoidal, and make fire grate upper surface level and smooth, during burning, heating surface area is large, and between tube and tube, interval is little, not easily card slag, sufficient combustion; Spacing before fire grate tube and tube reduces from top to bottom successively, and namely fire grate arrangement is more and more closeer, cinder can be cleared up in layering, avoid easy card slag in prior art, the defect of waste coal.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural principle schematic diagram of the present utility model;
Fig. 2 is single fire grate structure principle schematic in the utility model Fig. 1.
Shown in figure: 1. body of heater, 2. upper furnace door, 3. lower furnace door, 4. cleanout door, 5. fire grate, 6. air inlet.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As illustrated in fig. 1 and 2, described clean type coal boiler, be characterized in comprising body of heater 1, described body of heater 1 is disposed with from top to bottom upper furnace door 2, lower furnace door 3 and cleanout door 4, described lower furnace door 3 is set to multiple from top to bottom, be provided with one deck fire grate 5 in each lower furnace door 3, body of heater 1 both sides are also provided with air inlet 6.
Further, described fire grate 5 is set to inverted trapezoidal pipe and is arranged in order formula structure, and the spacing between the inverted trapezoidal pipe in every layer of fire grate reduces successively from upper strata to lower floor.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
