Abstract

The utility model relates to a vertical boiler with a horizontal water pipe, which is an improvement for a boiler, and the utility model is a vertical secondary-combustion boiler adopting mechanical or natural ventilation. The utility model is characterized in that a horizontal water pipe heating surface and a heat insulating layer made of fireproof materials are arranged in an inner boiler barrel, and a secondary air pipe and a single-layer fire grate are arranged in the heat insulating layer; the upper part of an outer boiler shell is provided with convex air heads, the lower part of the outer boiler shell is provided with U-shaped lower feet, and the lower part of a horizontal water pipe at the upper part of a boiler door is provided with a convex arch. The utility model can use bad-quality coal, and has the advantages of energy saving, smoke elimination, dust removal and high heat efficiency.

Description

Vertical boiler with horizontal water tube

The utility model is the improvement to boiler, is a kind of vertical boiler with horizontal water tubes that adopts machinery or gravity-flow ventilation.

At present, existing boiler has vertical double fire grate hot water (steam) boiler, the vertical hot water of binodal fire tube (steam) boiler etc., and there is double-layer grate its inside, and body of heater is oval-shaped, internal structure is welded into " U " shape heating surface with steel plate, the welding of employing angle welding, its manufacturing process complexity, weld seam is easy to crack during burning, service life is low, adopt force ventilation, fuel combustion is not thorough, wastes energy.

The purpose of this utility model provides a kind of vertical boiler with horizontal water tubes, has increased the heating surface of boiler, has improved the thermal efficiency of boiler.

The utility model content Description:

The utility model is a kind of vertical boiler, it is characterized in that in interior drum, having horizontal water tube Shou Re Mian And to be provided with the refractory material heat-insulation layer, in heat-insulation layer, be furnished with secondary air channel, twice gravity-flow ventilation, also can adopt force ventilation, the individual layer fire grate has convex public attention on the top of outer boiler hull, the bottom is that U-shaped is got a foothold, and a convex arch made from the alumina cement refractory material is arranged in door upper part horizontal water tube bottom.

The utility model vertical boiler with horizontal water tubes adopts the burning of natural wind secondary wind, also can adopt force ventilation, use low fire coal inferior, energy savings, smoke medicining dust-removing effect is good, below smoke discharge amount Da Lingeman 1 degree, the thermal efficiency is up to more than 70%, the body of heater circle, and floor space is little, manufacturing process is simple, can be widely used in heating such as enterprises and institutions, office, school, restaurant, has a bath, steamed rice, supplying drinking water.

Embodiment:

Fig. 1 is vertical boiler with horizontal water tubes overall structure figure.

Among the figure: 1 is Pressure gauge; 2 is convex public attention; 3 is water gage; 4 is water nozzle; 5 is horizontal water tube; 6 is secondary air channel; 7 is heat-insulation layer; 8 is fire door; 9 is fire grate; 10 is ashpit; 11 is blower fan; 12 are U-shaped leftover bits and pieces; 13 is blowoff valve; 14 for cleaning hand hole; 15 is water supply valve; 16 is interior drum; 17 is outer boiler hull; 18 is main air valve; 19 is impact tube; 20 are the convex arch.

The utility model is vertical circular boiler, its outside is circular outer boiler hull, in have circular in drum, outer boiler hull and interior drum form with the A3 welded steel plate, the bottom of outer boiler hull is provided with ashpit, its top is the individual layer casting furnace grate, be fire door above the fire grate, convex public attention is arranged at the top of outer boiler hull, and main air valve and Pressure gauge are arranged at the top of convex public attention, discharge steam by main air valve, for steamed rice and drinking water; Be provided with water gage and water nozzle on the top of interior drum, can observe water level and supplying drinking water in the stove; In interior drum, be furnished with horizontal by the horizontal water tube at 6 degree inclinations angle, increased the heating surface of boiler, improved the thermal efficiency of boiler; The heat-insulation layer that useful alumina cement refractory material is made below horizontal water tube, be furnished with in the heat-insulation layer at 4 uniform secondary air channels of circumferencial direction, the feeding natural wind is combustion-supporting, and unburned gas is fully burnt, improve the thermal efficiency of boiler, flue gas enters chimney by impact tube; The bottom of outer boiler hull is that U-shaped is got a foothold, and has increased the intensity that boiler is got a foothold, and blowoff valve is arranged on U-shaped is got a foothold and clean hand hole, can get rid of incrustation scale, is water supply valve on the top of cleaning hand hole, adds cold water by water supply valve in stove; In door upper part horizontal water tube bottom a convex arch made from the alumina cement refractory material is arranged, have in 4 uniform holes of circumferencial direction on the convex arch, corresponding with secondary ventiduct, flue gas passes through from the hole, feeds secondary wind and fully burns.
