Abstract

The utility model relates to a novel atmospheric hot-water boiler for raising the heat efficiency of a boiler and reducing environment pollution. The heating area of a boiler of the utility model adopts three vertical annular water jackets, and smoke channels are arranged among the water jackets. Smoke gas is exhausted to the atmosphere after vertically and reversely passing through three return strokes among the water jackets. Thus, the flow and the flow rate of the smoke gas are prolonged and raised, which is favorable for heat exchange, reduces the exhaust smoke temperature and the heat loss and is convenient for sedimentation of dust particles, and the dust concentration and the blackness of the exhausted smoke are reduced. The utility model is provided with a soot discharging opening at the lower part of the middle water jacket for avoiding the influence on the flow of smoke gas caused by excessive soot deposition at the lower parts of the smoke channels, and the soot can be periodically discharged.

Description

Vertical normal-pressure hot-water boiler

The utility model relates to a kind of efficient energy-saving, vertical normal-pressure hot-water boiler that smoke medicining dust-removing effect is good.

Problems such as it is big that existing vertical normal-pressure hot-water boiler generally exists the furnace water cooling degree, and burning condition is relatively poor, and flue gas flow is short, exhaust gas temperature is high, and smoke medicining dust-removing effect is poor, and the thermal efficiency is on the low side.

The utility model is intended to overcome above-mentioned deficiency, for the user provides a kind of novel hot-water boiler.The existing enough heat exchange areas of this boiler are unlikely that again furnace water cooling is spent greatly.Therefore, improved burning condition, improved fire box temperature, it is more abundant that fuel combustion is got, and shortened the time that fires greatly, saved fuel.The heating surface of this boiler has adopted three vertical ring-shaped water jackets, be flue between water jacket and the water jacket, they are heating surface, play a part brick baffle again simultaneously, flue gas is along vertically rhetorical question between the water jacket, after three backhauls, to atmosphere, so both prolonged the flow process of flue gas by chimney row, improved the flow velocity of flue gas, help the heat that heating surface can absorb flue gas fully, greatly reduce exhaust gas temperature, reduced heat loss, save fuel and improved the thermal efficiency, be beneficial to simultaneously the sedimentation of soot dust granule again, reduced dust content and the blackness in the smoke evacuation, alleviated pollution environment.

The utility model has adopted following structure: it is a kind of vertical normal-pressure hot-water boiler, heating surface by vertical annular outer water jacket 7, middle water jacket 9, inner water sleeve 8, forms, a fire door 3 and ash 1 respectively established in the boiler bottom.A casting furnace grate 2 is arranged in the fire door, and the course of work is as follows: coal (have bituminous coal or anthracite all can) by manually throwing to fire grate from fire door, is closed fire door, suitably opens the ash door, and wind is entered by the ash door, and burning is participated in the coal seam that sees through on the fire grate.Product after the burning, i.e. high temperature pyrotechnics is by upwards washing away middle water jacket heating surface outward along between outer water jacket and the middle water jacket around the burner hearth, it is promptly reverse after high-temperature flue gas arrives the stove internal upper part, in washing away again downwards, the inner water sleeve heating surface, and then oppositely, upwards through chimney 13, row to atmosphere.This process is exactly the burning of fuel and the product after the burning process that to be high temperature pyrotechnics carry out heat exchange with the interior working medium of heating surface.Flue gas is through the mobile heating surface that washes away of three backhauls, and temperature just descends gradually.Meanwhile, the dustiness in the flue gas also significantly reduces, and heating surface has also been avoided the deposition of cigarette ash owing to be vertically arranged, helps the heat transfer of high-temperature flue gas to heating surface.

Water cyclic system Natural Circulation in the stove, system's backwater just are divided into two parts by return pipe 15, after entering outer water jacket: a part enters outer water jacket, and another part is by descending water connecting leg 4 and middle water connecting leg 6, entering middle water jacket and inner water sleeve respectively.Water washing away in the water jacket through high temperature pyrotechnics, temperature rises, the molecule of water expands and lightens, make automatically and upwards flow, in hot water in the water jacket by last water connecting leg 10, converge with hot water in the outer water jacket, after hot water in the inner water sleeve rises also with outer, in, interior hot water converges, in the whole stove hot water by outlet pipe 14, draw, use for system.

The outer water jacket foot of boiler is established a blow-off pipe 16, regularly discharges the interior body refuse dirt of stove for the operator.

Upper furnace is established a movable ash-removing mouth 5, in operator's discharging regularly, the soot dust granule that falls in the flue between the inner water sleeve and the chimney.

Baffle plate 12 is established on chimney top one, uses when the boiler pressuring fire for the operator.

The boiler topmost is established a normal pressure pipe 11, leads to outdoorly, does not adorn any valve on this pipe, guarantees during boiler operatiopn that furnace pressure communicates with atmosphere.Thereby guarantee the safe and reliable of boiler operatiopn.

The utility model is more simple in structure compared with prior art, make easily, cost is low and burning condition is good, coal consumption is low, it is fast to fire, flue gas flow is long, heat exchange is thorough, flue dust is few, exhaust gas temperature is low, the thermal efficiency is high and floor space is little, installing simply, easy to operate, is the ideal high equipment of warming oneself of small business unit and urban and rural residents building.
