Description

The reclining posture hot-water boiler

The utility model relates to coal-burning boiler, especially a kind of normal pressure reclining posture hot-water boiler.

Normal pressure coal-fired hot-water boiler in the market, ubiquity shortcomings such as the thermal efficiency is low, environmental index is poor, floor space is big, cost is high, power consumption is many, can not satisfy user's requirement.

The purpose of this utility model is the defective that overcomes prior art, providing a kind of is the hot-water boiler of feature with the reclining posture body of heater, can obtain horizontal chamber furnace (oven) can the optimal placement fire grate and combustion chamber, vertical heater can realize the two-fold advantage of best heat-transfer area layout, thermal efficiency height, reduced dust-exhausting quantity, floor space is little, and cost is low, little power consumption.

The purpose of this utility model realizes as follows: it is made of upper furnace body and lower furnace body two parts.Upper furnace body is a cylinder, and lower furnace body is a cuboid, and upper and lower body of heater is made respectively, transported, and can be assembled into one easily in the erecting bed.Upper furnace body is made up of the heating surface that cylindrical water jacket and convection current heat pipe constitute, and by dividing plate water jacket is divided into the first half and two hydrospaces of Lower Half, and the upper furnace body top is provided with chimney.Two parts before and after lower furnace body is divided into by fire division wall, its front portion is divided into three parts from top to bottom again: water-cooled grate top is new coal combustion chamber, is the hyperthermia radiation secondary furnace between water-cooled grate and the casting furnace grate, is cinder chamber under the water-cooled grate.The lower furnace body rear portion is a rear hearth, radiation heating-surface and the dust chamber formed by the radiation heat pipe in the rear hearth, on the fire division wall between rear hearth and the hyperthermia radiation secondary furnace fireworks channel that the two is communicated is arranged, the top of upper furnace body is the backwater preheating zone, the bottom of upper furnace body is the final thermal treatment zone of boiler hot-water, and it is whole that upper furnace body and lower furnace body are linked to be a water circulation by circulating water pipe.

Can boiler be set in the bottom of upper furnace body, it is an independent water loop body, and quirk gate control fire amount size is arranged at the bottom, and can close quirk behind boiling water.

Fire coal is put into new coal combustion chamber by the upper furnace door of lower furnace body, and a required wind is regulated by fire door.Fire coal anti-burning on water-cooled grate, high temperature pyrotechnics enters the hyperthermia radiation secondary furnace through coal seam and water-cooled grate, unburnt carbon granule of part and lime-ash also drop on the casting furnace grate, high temperature pyrotechnics mixes with secondary wind from lower fire grating under the baking of the radiation effects of wall high-temperature radiation material and upper and lower fire grate charcoal fire and obtains the best combustion condition, and burning very fully, fully.Simultaneously, because the volume of hyperthermia radiation secondary furnace layout is bigger, flue gas obtains dilatation, and the cigarette prompt drop is low, and carbon granule and dust obtain sedimentation under the inertia force effect.Then, the fireworks channel of high temperature pyrotechnics on partition wall enters the lower furnace body rear hearth, carry out radiation heat transfer at this, flue gas is making progress by producing baffling behind the fireworks channel simultaneously, and further dilatation, flue dust obtains sedimentation for the second time, the flue gas baffling that is purified upwards enters upper furnace body and carries out heat convection, at this moment flue gas volume reduces after heat release very soon, the upper furnace body combustion space increases relatively, simultaneously flue gas in uphill process constantly baffling and with the convection current tube bank collision of being heated, dust obtains sedimentation for the third time, last flue gas enters atmosphere through the upper boiler chimney.The stove outer circulating tube is set in the body of heater both sides connects the upper end of the upper furnace body first half and the lower end of lower furnace body, lower end at the upper furnace body first half is provided with return pipe, upper end in the upper furnace body Lower Half is provided with hot water outlet, and return pipe is connected outside circulation water for heating road with hot water outlet.Cold water or the backwater return pipe through upper furnace body first half lower end enters the upper furnace body first half and be transported to lower furnace body lower end water inlet pipe mouth by two wing furnace outer circulating tubes after heating, the heating rising enters the upper furnace body bottom in lower furnace body then, continue heating and rise to the upper furnace body Lower Half, heating rises to hot water outlet and delivers to the user through water pump again.Arrange two to four groups of cinder cleaning holes respectively in upper furnace body bottom and lower furnace body bottom, arrange a total blow-off pipe at rear, lower furnace body bottom.

The utility model reclining posture hot-water boiler, owing to adopt the reclining posture structure, the thermal efficiency is higher, reaches 78%, is higher than 6 percentage points of national standards; Owing to adopt the design of flue gas three bafflings, make flue dust in stove, obtain abundant sedimentation, the actual measurement dust content is 130mg/mm ³Below; Reasonably volume, air distribution design are fully burned high-temperature flue gas, and Lin Geman is below the 0-0.5 level in smoke evacuation; This boiler adopts the on-mechanical coal, gravity-flow ventilation, and the boiler body floor space is with 1/2 of power machine operation stove, cost reduces 1/3, economize on electricity 60%.This stove adds independently boiler simultaneously, and drinking water respectively becomes a system with stove water, has guaranteed the health of drinking water, and drinking-water, heat supply are neglected neither, and realizes multi-functional.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing is the structural representation of the utility model reclining posture hot-water boiler.
