Description
Technical field
The present invention relates to the boiler technology field, particularly a kind of Horizontal internal-combustion wet-back formula boiler.
Background technology
Along with the pay attention to day by day of country to environmental protection, combustion gas more and more gets more and more people's extensive concerning as a kind of clean energy resource.Energy problem and environmental problem become the focus that people pay close attention to now day by day, and the harm that the high pollution of coal causes environment has caused people's common recognition.The development combustion gas acts as a fuel for industry and has civilianly become desirable selection, and gas fired-boiler will occupy more and more important position in our life.At first natural gas is a kind of energy of cleaning, contains impurity few, the also corresponding minimizing of harm environment accompanying gas that burning produces.The 2nd, the height of natural gas heat, cleaner, the coefficient of heat transfer of corresponding boiler heat exchange is high, will reduce accordingly like this consumption of the boiler raw material such as steel.Along with gas fired-boiler development, it is high that wet-back boiler has the thermal efficiency as a kind of commonplace boiler, reaches 90% the thermal efficiency, occupies very large ratio on civil boiler market.
Wetting back-type three pass fire pipe boilers are that boiler furnace flue connects return combustion chamber, then return combustion chamber is connected with the first return smoke fire tube bundle with the front smoke box tube sheet, with the second return smoke fire tube bundle, connect front flue tube sheet and rear smoke-box tube sheet.Combustion gas is burnt at flue, produces flue gas, through return combustion chamber, after the first return smoke fire tube bundle, arrives front smoke box, smoke box after the second return smoke fire tube bundle arrives again, then from flue on smoke box discharge outside boiler.Front smoke box and rear smoke box end socket are built with refractory cement.There is following shortcoming in existing three pass fire pipe boilers:
1. maintenance inconvenience: the end socket of boiler is very heavy, and boiler power is larger, and this kind of drawback is more obvious.If, in long emerged in operation boiler's tube-plate problems of crack, at first check that the concrete place of boiler problem is exactly a problem, add due to the end socket heaviness, end socket is dismantled and reset all very difficult.
2. heat exchange is insufficient: the smoke box end socket of boiler, by thick refractory cement cast, is to prevent that high-temperature flue gas from washing away and causing end socket to burn out, and affects boiler operatiopn on the one hand; To make boiler more fastening on the other hand.But the steel that boiler is used fully do not use in heat exchange and go, and cause heat exchange insufficient, cause steel waste and heat loss due to exhaust gas.
Summary of the invention
The invention provides a kind of Horizontal internal-combustion wet-back formula boiler, in order to solve existing wetting back-type formula boiler maintenance inconvenience and the inadequate problem of heat exchange.
Technical scheme of the present invention is such realization: a kind of Horizontal internal-combustion wet-back formula boiler, comprise stove cylinder, flue, return combustion chamber, front smoke box and rear smoke box, flue connects return combustion chamber, return combustion chamber is communicated with front smoke box by the first return smoke fire tube bundle, front smoke box is communicated with rear smoke box by the second return smoke fire tube bundle, front smoke box and rear smoke box are arranged in the stove cylinder, and flue is through front smoke box and rear smoke box.
Wherein, preferably, front smoke box is provided with the front smoke box jacket pipe at flue through place, and rear smoke box is the smoke box jacket pipe after flue is provided with through place.
Wherein, preferably, stove cylinder front end is provided with front head, and the position of the corresponding front smoke box of front head is provided with the front smoke box manhole.
Wherein, preferably, the inwall of the front head that flue stretches out is provided with the refractory cement piece.
Wherein, preferably, the stove tube rear end is provided with rear head, and the position of the rear smoke box that rear head is corresponding is provided with rear smoke box manhole.
Wherein, preferably, the inwall of the rear head that flue stretches out is provided with the refractory cement piece, and flue partly is provided with flame-observing hole stretching out rear head.
Wherein, preferably, see fire and also be provided with manhole in hole site, manhole is communicated with return combustion chamber through rear smoke box.
Wherein, preferably, front smoke box is communicated with and stretches out the outer front smoke box blow-off pipe of stove cylinder.
Wherein, preferably, rear smoke box is communicated with and stretches out the outer rear smoke box blow-off pipe of stove cylinder.
The present invention has following beneficial effect:
1. maintenance is convenient: the present invention is provided with manhole and boiler's tube-plate on the boiler outside head, and any parts such as pyrotechnics tube bank have problems and all can open very easily and carry out inspection and maintenance.
2. heating surface strengthens: its smoke box of wet-back boiler originally is partly directly to be cast with refractory cement, prevent that dry combustion method from burning out, do not participate in carrying out boiler heat exchange, now, smoke box is built in the water in the stove cylinder, allows its sustainable participation boiler heat exchange, like this, the boiler heat exchange face strengthens, and exchange capability of heat is strengthened; And the temperature degree of discharging obviously reduces, and environmental protection has also been saved fuel.
3. saved material and produced the duration: the use amount of the refractory cement of original wet-back boiler is very large, the present invention need be not corresponding at smoke box end socket refractory cement partly is set, only at flue, stretch out the end socket part and used a small amount of refractory cement for fastening burner, make simple, duration reduces, and structure is also more rationally compact.
