Description

Fire coal is counter to burn more backhaul environment protection hot-water boilers
Technical field
The present invention relates to a kind of anti-burning water-heating boiler of fire coal, the heat convection of especially a kind of anti-burning water-heating boiler of fire coal is filled It sets.
Background technique
Coal-fired anti-burning water-heating boiler has the features such as high combustion efficiency of fuel, smoke evacuation dust is low referred to as environment-protection boiler. In the prior art, coal-fired anti-burning water-heating boiler has vertical rectangular bodily form furnace body, and furnace body has collet furnace wall, and collet has above furnace wall Water outlet has water inlet below collet furnace wall, and furnace has reverse burning furnace thorax below intracorporal front side, and reverse burning furnace thorax has and collet furnace wall The collet hearth wall communicated has the round tube fire grate communicated with collet furnace wall and collet hearth wall, circular tube furnace below collet burner hearth There is cinder chamber below row, the antetheca of reverse burning furnace thorax has fire door, and the antetheca of cinder chamber has lime-ash door, the intracorporal rear side of furnace and top There is convective heat transfer device, convective heat transfer device has the tubulation and baffle plate communicated with collet furnace wall, convective heat transfer device in furnace body Top have a smoke outlet, there is overfiren air port in the front side of reverse burning furnace thorax once air port on front side of cinder chamber.
In use, from water inlet continuously to collet furnace wall, collet hearth wall and the round tube fire grate of coal-fired anti-burning water-heating boiler Interior plus water, allows coal to burn on the round tube fire grate in reverse burning furnace thorax, the high-temperature flue gas of generation enters the column of convective heat transfer device Between pipe pipe, it is discharged upwards and after horizontal three processes being folded to from smoke outlet, the heat collet hearth wall that coal combustion generates, Heat supply can be continuously discharged from water outlet in water in round tube fire grate and collet furnace wall, hot water.
This anti-burning water-heating boiler of fire coal has following deficiency:
1. water is walked in pipe in convective heat transfer device, between high-temperature flue makes pipe leave with rage, the flow velocity of high-temperature flue gas is lower, heat transfer system Number is smaller, and after heat convection, there are also certain heats for the flue gas being discharged from smoke outlet, causes high fume temperature, heat utilization Rate is low, the boiler thermal efficiency is not very high;
2. reverse burning furnace thorax only has one layer of fire grate, when burning on fire grate, some uncombusted coals can fall down coal from fire grate, Cinder chamber is dropped to, lacks burning condition in cinder chamber, causes fuel availability low.
Summary of the invention
The purpose of the invention is to overcome above-mentioned deficiency, propose that a kind of fuel availability is higher, the thermal efficiency of boiler compared with High fire coal is counter to burn more backhaul environment protection hot-water boilers.
The present invention is achieved using the following method.
It is coal-fired it is counter burn more backhaul environment protection hot-water boilers and have vertical rectangular bodily form furnace body, furnace body has collet furnace wall, collet furnace wall Top have water outlet, have water inlet below collet furnace wall, there is reverse burning furnace thorax below the intracorporal front side of furnace, reverse burning furnace thorax have with The collet hearth wall that collet furnace wall communicates has the circular tube furnace communicated with collet furnace wall and collet hearth wall below collet burner hearth It arranges, has cinder chamber below round tube fire grate, the antetheca of reverse burning furnace thorax has fire door, and the antetheca of cinder chamber has lime-ash door, and furnace is intracorporal There are convective heat transfer device in rear side and top, and convective heat transfer device has the tubulation communicated with collet furnace wall and collet baffle plate, furnace body There is smoke outlet above interior convective heat transfer device, there is overfiren air port in the front side of reverse burning furnace thorax once air port on front side of cinder chamber, There is vertical threaded flue in the rear wall of collet furnace wall, has lower smoke box, the upper orifice and furnace of smoke pipe below the rear wall of collet furnace wall Smoke outlet above body communicates, and the lower nozzle of threaded flue is communicated with lower smoke box, and lower smoke box has outlet flue and breast hole, cinder chamber Lower section have lower fire grating, the lower section You Xia cinder chamber of lower furnace wall, there is lower lime-ash door in lower cinder chamber.
There is vertical threaded flue in the rear wall of collet furnace wall of the present invention, the flue gas being discharged from smoke outlet passes through screw thread cigarette The discharge of Guan Houcong outlet flue, flue gas in threaded flue is rotational flow, and the fast speed of air-flow, heat transfer coefficient is larger, It can recycle from the heat in the flue gas that smoke outlet is discharged, improve the thermal efficiency of boiler.The heat output of threaded flue is equivalent to flat 1.7 ~ 1.8 times of straight smoke pipe can make boiler save steel using threaded flue quantity than significantly reducing using straight smoke pipe quantity Material, reduces manufacturing cost, and threaded flue has the effect " from cleaning ", under normal operating conditions, threaded flue to dry and soft cigarette ash Interior dust stratification is than straight smoke pipe much less.
There is two layers of fire grate below reverse burning furnace thorax of the invention, upper layer round tube fire grate is main combustion chamber fire grate, when normal work, Only upslide coal, fresh fuel preheated, dry, volatile matter evolution, igniting combustion on the round tube fire grate of upper layer are arranged to upper layer circular tube furnace The processes such as burning, when the slag blanket of round tube fire grate initially forms spent anthracite, anthracite is with volume-diminished or pokes fire, by upper layer The gap of round tube fire grate is left out by mistake to that can burn away on lower layer's fire grate, and fuel combustion is abundant, reduces coal consumption.
