Abstract
The utility model relates to a gas-fired hot water boiler, in particular to a wet-back gas-fired hot-water modular cast iron boiler. The boiler comprises a boiler casing, a boiler body arranged in the boiler casing and a plurality of combustion tubes, wherein the top part of the boiler casing is provided with an outlet flue; the boiler body is formed by connecting a plurality of radiators in series; the lower parts of the radiators are provided with cavities which pass through two side walls of the radiators; a plurality of pyramidal bulges are arranged at the outside upper parts of the radiators, wherein the lower part of the first radiator is provided with a water inlet pipe; the upper part of the last radiator is provided with a water outlet pipe; the water inlet pipe and the water outlet pipe are communicated with the inner cavity of each radiator respectively; and the combustion tubes are arranged between adjacent radiators respectively. By adopting the radiator structure provided by the utility model, heat in a hearth box is effectively absorbed as heat absorption area is enlarged, and the exhaust gas temperature of the boiler is reduced, thus the heat efficiency of the boiler is significantly increased.
Description
Technical field
The utility model relates to a kind of gas-fired water heating boiler, particularly relates to a kind of wetting back-type gas and hot water cast iron module boiler.
Background technology
The factor that influences boiler thermal output mainly is the height of boiler smoke temperature and the size of heat exchange area, and the smoke temperature is high more, and the heat loss of boiler is big more, causes the thermal efficiency of boiler to reduce.The smoke temperature of cast iron module boiler causes the so high reason of smoke temperature to be that the heating surface area of stove sheet and stove sheet can not fully absorb the heat in the stove hall basically more than 200 ℃ in the market.Therefore, the flue gas of high temperature has not only reduced the heating rate of boiler, and the high temperature in the burner hearth also causes shorten the service life of boiler.
The utility model content
Technical problem to be solved in the utility model is to solve the problem that the stove sheet fully absorbs the heat in the stove hall.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of wetting back-type gas and hot water cast iron module boiler, comprise boiler jacket and be arranged on boiler jacket interior body of heater and some combustion tubes, the top of described boiler jacket is provided with outlet flue, described body of heater is arranged in order by some stove sheets and forms and the upper and lower of each stove sheet is communicated with respectively and is in series, the lateral surface of described stove sheet is provided with several projections, wherein the bottom of first stove sheet is provided with water inlet pipe, the top of last a slice stove sheet is provided with outlet pipe, and described combustion tube is separately positioned between the adjacent stove sheet.
In the such scheme, the bottom of described stove sheet is provided with the cavity of straight-flow furnace sheet two side.
Described stove sheet is the rectangle sheet, and described projection is a pyramid-shaped, is arranged on the two side of stove sheet cavity top.
The outer wall of described boiler jacket is provided with resistant to elevated temperatures warming plate.
Stove sheet in the utility model is the rectangular configuration of casting, top is covered with cast iron heat absorption cone, the bottom is provided with the cavity of straight-flow furnace sheet two side, combustion tube is separately positioned between the adjacent stove sheet, around the stove sheet cavity part is that back and bottom are the boiler blow-down water circulatory system, and this structure has not only increased endotherm area, and the heat in the burner hearth is effectively absorbed, and reduced the smoke temperature of boiler, improved the thermal efficiency of boiler greatly.
