Abstract
A horizontal water-tube atmospheric hot-water boiler is composed of coal hopper, reciprocating grate, front and back arches, plate-type water-cooled walls, convection heat-exchange tube bundles symmetrical at both sides, front and back smoke-leading holes for connecting convection flues at both sides, and boiler barrel.
Description
The utility model relates to a kind of horizontal water pipe atmospheric hot-water pot of improvement.
Commercially available A type horizontal water pipe pressure boiler generally adopts the water pipe water wall structure, the sealing of the not easy-to-use refractory liner of the water pipe water-cooling wall of both sides and front and back, flue gas easily reveal and the ascent of conducting heat less than 1, heat transfer efficiency is low, the steel consumption height.
The utility model patent of CN91209267.X discloses a kind of " horizontal mechanical burning multifunctional atmospheric hot-water boiler ", this boiler is made of coal bunker, reciprocal grate, face arch, rear arch, board-like water-cooling wall, advection smoke pipe, balanced reservoir, drum, flue and slag ground, and its shortcoming is that the convection current smoke pipe of level is easily stopped up by the flying dust of sedimentation.
The purpose of this utility model is to design a kind of burner hearth sealing, catches fire easily, deashing is convenient, it is simple to make, save the horizontal water pipe normal-pressure hot-water boilers of steel.
Horizontal water pipe normal-pressure hot-water boiler of the present utility model is by coal bunker, reciprocal grate, face arch, rear arch, board-like water-cooling wall, drum, flue and slag bath constitute, it is characterized in that board-like water-cooling wall being set in the front and back and the both sides of burner hearth, in the burner hearth bilateral symmetry water pipe convective heat exchange tube bundles is set, front and rear at burner hearth is provided with face arch and rear arch, the rear arch upper and lower surface is heated, accumulation of heat, cigarette hole, back is set on rear arch, back cigarette hole communicates with the convection pass of a side, preceding cigarette duct in being arranged on burner hearth feeds the convection pass of opposite side, and the face arch upper and lower surface is heated, accumulation of heat.Because front and back sagitta intermediate temperature regenerator has improved elimination dirt and ignition speed effectively, has improved fix density of radiate heat exchange.This A type turning flue is arranged on to make in the burner hearth and obtains making simply and saved steel.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the front view of the utility model boiler structure schematic diagram,
Fig. 2 is its positive top view,
Fig. 3 is its side view,
As shown in the figure, 1 is coal bunker, and 2 is coal gate, 3 is reciprocal grate, and 4 is floss hole, and 5 is face arch, 6 is rear arch, and 7 are logical air pipe, and 8 is manhole, 9 is mouth, and 10 is the float hydraulic valve, and the Dalian Zhuanghe cuts down door two factories and produces, be used for controlling automatically the water level of boiler body, 11 is burner hearth, and 12 is shell, 13 is outlet pipe, and 14 is fire door, and 15 are the deashing lid, 16 is the air port, and 17 is mud hole, and 18 is motor reducer, 19 is first convection bank, and 20 is the left side furnace wall, and 21 is exhaust opening, 22 is second convection bank, and 23 is the right side furnace wall, and 24 is observation door, 25 is return pipe, and 26 is ash dropping hopper, and 27 is shoot door, 28 is base, and 29 is blower fan, and 30 is the water level meter, 31 is board-like water-cooling wall, and 32 is drum.
Coal is added coal bunker 1, regulate coal input quantity with coal gate, coal burns the remaining slag in back through mud hole 17 discharges on reciprocal grate 3.
The high-temperature flue gas that coal combustion produces enters first convection bank 19 by outlet flue 9 after face arch 5 and rear arch 6 reflections, the coal ash of deposition is discharged through deashing lid 15 in the burner hearth.After flue gas and first convection bank, 19 heat exchange, enter second convection bank 22 and continue heat exchange through being located at burner hearth inner flue mouth 4, the dust stratification in first and second convection tube space is discharged from ash dropping hopper 26, and is last, and flue gas enters emptying behind the chimney from outlet flue 21.
Hot water draws water from outlet pipe 13 usefulness pumps, enters water-cooling wall 31 by return pipe 25 after the heating system heat release, is used for heating after the circulation heating once more.
As mentioned above, owing to adopt the convection bank heat exchange, can not cause dust stratification to stop up, dust stratification also is easy to remove.After removing furnace wall 21 and 23, all weld the nothing left of part knocking, thereby be convenient to make maintenance, overcome the shortcoming that general normal-pressure boiler is difficult to keep in repair.Owing to adopt the water pipe heat exchange, the coefficient of heat transfer is than smoke pipe height, thereby saved steel, reduced cost.Adopt the float hydraulic valve can effectively control the water level of boiler, have little time to close the valve on the water return pipeline by ground when having avoided general normal-pressure boiler to have a power failure suddenly and the boiler spilling water phenomenon that causes.
Test and on probation showing, the smoke dust discharge concentration of this boiler combustion three class bituminous coal is less than the 200mg/ cubic meter, and lingemann blackness reaches the first discharge standard of international regulation less than 1 degree.
Claims (2)
1, a kind of horizontal water pipe normal-pressure hot-water boiler is made of coal bunker, reciprocal grate, face arch, rear arch, water-cooling wall, drum, flue and drum, it is characterized in that being provided with board-like water-cooling wall in the front and back and the both sides of burner hearth.
2, hot-water boiler as claimed in claim 1 is characterized in that being provided with convective heat exchange tube bundles in the burner hearth bilateral symmetry, is provided with the front and back smoke guiding hole of the convection pass that connects both sides in burner hearth.
