Abstract
The utility model discloses a kind of boiler improving fume afterheat utilization rate, relate to boiler technology field.Comprise burner hearth, form hydroecium, form smoke discharging pipe between boiler inner wall and boiler casing between the outer surface of described burner hearth and boiler inner wall, the mouth of delivering coal of burner hearth is arranged on the top of burner hearth, and slag-drip opening is arranged on the bottom of burner hearth; The bottom of hydroecium is provided with water inlet, and top or the middle part of hydroecium are provided with delivery port; Described burner hearth is obliquely installed, and the outlet flue of burner hearth communicates with the mouth of delivering coal of burner hearth.The heat energy that the coal of burner hearth combustion produces heats from the inner side of hydroecium, and smoke discharging pipe heats from the outside of hydroecium, and the waste heat of flue gas is utilized again, and the inside and outside of hydroecium is heated simultaneously, improves the programming rate of water.The burner hearth be obliquely installed and the outlet flue of burner hearth communicate with the coal feed point of burner hearth, and the to be combusted coal of high-temperature flue gas to middle part and top that the coal being in burner hearth bottom burning is produced heats and dry, and improves burning of coal rate.
Description
Technical field
The utility model relates to boiler, especially a kind of boiler improving fume afterheat utilization rate.
Background technology
China is coal reserves, production, consumption big country, the billions of ton of annual coal consumption, and the serious problems such as the high pollution that coal burning brings, maximum discharge, the wasting of resources are obvious to all, and the problem in its future can't bear prediction especially; Economic development, resources conservation, environmental protection are related to the great cause success or failure of the rejuvenation of the Chinese nation.
The flue-gas temperature that current hot-water boiler is discharged is higher, generally needs can be discharged in air after flue gas cooling processing, which greatly enhances the cost that boiler uses.
Summary of the invention
The purpose of this utility model is to propose a kind of use cost improving high-temperature flue gas utilization rate, reduce boiler.
For achieving the above object, following technical scheme is provided:
A kind of boiler improving fume afterheat utilization rate, comprise burner hearth, hydroecium is formed between the outer surface of described burner hearth and boiler inner wall, smoke discharging pipe is formed between boiler inner wall and boiler casing, the mouth of delivering coal of burner hearth is arranged on the top of burner hearth, slag-drip opening is arranged on the bottom of burner hearth, and mouthful place that delivers coal is provided with baffle plate of delivering coal; The bottom of hydroecium is provided with water inlet, and top or the middle part of hydroecium are provided with delivery port; Described burner hearth is obliquely installed, and the outlet flue of burner hearth communicates with the mouth of delivering coal of burner hearth.The heat energy that the coal of burner hearth combustion produces heats from the inner side of hydroecium, and smoke discharging pipe heats from the outside of hydroecium, and the waste heat of flue gas is utilized again, and the inside and outside of hydroecium is heated simultaneously, improves the programming rate of water.The burner hearth be obliquely installed and the outlet flue of burner hearth communicate with the coal feed point of burner hearth, the to be combusted coal of high-temperature flue gas to middle part and top that the coal being in burner hearth bottom burning is produced heats and dries, improve burning of coal rate, further save the energy, cut the waste.When not needing to add coal in boiler, mouth of delivering coal is in closed condition, can prevent flue gas from discharging from mouth of delivering coal like this.
Further, also comprise scum pipe, described scum pipe is connected with slag-drip opening, bottom described scum pipe left side wall, outside chimb is set, chimb is provided with at least one bolt hole, be connected with scum pipe right side wall by hinge on the right side of deslagging baffle plate, the bolt hole matched be set on the left of deslagging baffle plate, and be bolted with the bolt hole that scum pipe left side wall bottom flange is arranged.When needs carry out deslagging, deslagging baffle plate is opened and carries out deslagging.And when not needing deslagging, deslagging baffle plate is in closed condition always, the dust that can prevent burning from producing like this is discharged into indoor from scum pipe, affects air quality.
Further, also comprise air blast, the exhaust outlet of described air blast is arranged in scum pipe.By air blast from the bottom of boiler to air blast in boiler, improve burning of coal efficiency.
Preferably, the exhaust outlet of described air blast is bent downwardly, and the dust that can prevent burning from producing like this drops on exhaust outlet, and is blocked by exhaust outlet, affects the effect of air blast.
