Abstract

The utility model relates to a hot ring and hot pipe normal pressure water heating boiler, particularly a civil water boiler. Water heating boilers which adopt hot pipes mostly uses an inverse combusting boiler type in the prior art, thus cold water grates which are easy to be broken still exist, and the hot pipes are only used on the top of a boiler with a nonideal effect. The purpose of the utility model is to provide a novel water heating boiler which simultaneously uses hot rings and hot pipes. The utility model is characterized in that the utility model is provided with an upper and a lower transverse water chambers, an upper and a lower layers of hot pipe groups, and a hot ring type inertia force dust remover is arranged between a water wall and a smoke chamber on the top of the utility model. The thermal efficiency and output force of a boiler are greatly enhanced by the structure, and the utility model has the advantages of low smoke expelling temperature, good dust removing effect, simple structure, low cost, easy repair and long service life. The utility model is a novel boiler type which is worth spreading.

Description

Thermal ring tube normal pressure water heating boiler

The utility model relates to the domestic hot water boiler, especially hot ring, heat pipe normal-pressure hot-water boiler.

At present, what hot-water boiler generally adopted is the anti-stove that burns, and this helps smoke abatement and dust control, but boiler thermal output and exert oneself just generally lowlyer, water-cooled grate tube also damages easily, and maintenance rate is higher, and smoke-box top heating surface is little, the heat loss due to exhaust gas height.For addressing the above problem No. 90222876.5, Chinese patent, the patent of title " heat pipe normal-pressure hot-water boiler ", disclose a kind of top and set up some heat pipes at the upper boiler smoke-box, be used to increase heating surface area, reduce the heat loss of smoke evacuation, obtained certain effect.Yet, still have boiler thermal output and exert oneself lowlyer, problem such as water-cooled grate tube is fragile, and the higher and smoke evacuation dedusting of maintenance rate is undesirable.

The purpose of this utility model is exactly at the existing in prior technology problem, and provides a kind of employing heat pipe and hot loop technique to improve boiler thermal output, reduces exhaust gas temperature, easy-maintaining, the novel normal-pressure hot-water boiler technical scheme of long service life.

The technical program is to realize like this, mainly be heat ring, the heat pipe normal-pressure hot-water boiler that constitutes by outer furnace wall 4, water wall 5, fire grate 14, burner hearth 13, water coal vapour generating means 2 and smoke exhaust pipe 6 etc., the special character of this programme has a following horizontal hydroecium 12 that communicates with water wall 5 that burner hearth 13 and smoke-box are separated above burner hearth 13, end at following horizontal hydroecium 12 is installed with secondary vane 3 connection burner hearth 13 and smoke-boxes, forms exhaust gases passes; The inner chamber of secondary vane 3 communicates with secondary air intake pipe 1, and the inwall of secondary vane 3 has fresh air inlet, and this fresh air inlet is 20 to 40 diameters to be arranged in 10 to 14 millimeters equally distributed holes; Have above the following horizontal hydroecium 12 one communicate with water wall 5 on horizontal hydroecium 11, and leave exhaust gases passes in the corresponding end of secondary vane 3, interspersed on the lower wall of last horizontal hydroecium 11 at least 30 equally distributed time heat pipes 10 are housed; The inwardly outstanding annular table of water wall 5 above last horizontal hydroecium 11, and intert on the lower wall of annular table be equipped with at least 40 equally distributed on heat pipe 9; Above water wall 5 annular table, be provided with hot ring type inertia force precipitator, described hot ring type inertia force precipitator is to insert furnace roof water wall 5 simultaneously by coaxial inside and outside two heat rings 7 and 8 to constitute, on interior heat ring 7 and outer heat ring 8, have mutual not corresponding exhaust hole, the baffle plate that connects space in its ring of a sealing on the tops that interior heat ring 7 stretches out the smoke-box part, and outer heat ring 8 stretches out and is connected a baffle plate that exhaust hole arranged between the interior ring of smoke-box top partly and water wall 5 annular table.And heat ring 7 and outer heat ring 8 all are metal sealed cavity ring sets in described, are filled with in its cavity that heat-conduction medium constitutes.

The utility model has saved flimsy cold water furnace grate tube owing to adopt single combustion chamber, has significantly reduced maintenance capacity.Make the flue gas route of burner hearth rising S-shaped because of being provided with upper and lower horizontal hydroecium again, this has not only increased the stroke and the resistance of flue gas, and has increased heating surface area.Add upper and lower heat pipe and hot ring type inertia force precipitator again, more improved the thermal efficiency and the dust removing effects of boiler.In addition, the easy-maintaining simple in structure of this programme, the low and long service life of production cost.As seen compared with prior art, the effect of this programme is extremely significant.
