Description
Technical field
The utility model relates to a kind of steam boiler.Belong to the heating equipment technical field.
For the sustainable development that adapts to national economy and the requirement of environmental protection, coal type fuel is progressively changed into oil, gas type fuel.Oil, gas type fuel are easy to carry and use, and are guaranteeing basically not produce environmental pollution under the good burning condition, and calorific capacity is high, and this is so that fuel-oil or fuel-gas boiler is realized operation automation, high efficiency.In recent years because fuel-oil or fuel-gas boiler is small, automaticity is high, easy for installation, and under various heating agents, can obtain very convenient and use flexibly, fuel-oil or fuel-gas boiler has obtained developing widely and using.
In the tradition fuel-oil or fuel-gas boiler, owing to reasons such as flue gas resistance, cold end corrosions, the exhaust gas temperature design all is higher than 150 ℃, the boiler of tail heating surface even be higher than 250 ℃ not, water vapour is in the superheated steam state in the flue gas, can not condense into aqueous water and emits the latent heat of vaporization, therefore, China is the same with other countries, adopts the low heat value of fuel as calculating benchmark in the boiler thermodynamic calculation.If can drop to exhaust gas temperature enough lowly, the water vapour that is superheat state in the flue gas will condense into aqueous water and emit the latent heat of vaporization.
We will be by the water vapour in the condensation flue gas, is called condenser boiler thereby reclaim the boiler that its latent heat of vaporization improves boiler thermal output.
China's condenser boiler also is in space state or starting stage substantially, and main cause is China to the understanding deficiency of condensing boiler is a major reason, and another reason is exactly that manufacturer is to the popularization of condensing boiler with research and develop ineffective.Along with China's economic technology development, efficiently utilize high-grade fuel, improve fuel availability, reach energy-conservation and the reduction of discharging purpose, be subject to the attention of government and all trades and professions.Since take oil or gas after fuel combustion, vapour content is high in the flue gas, condenser boiler is by the exhaust gas temperature of effective reduce fuel oil or gas fired-boiler, make the water vapor condensation in the flue gas emit the latent heat of vaporization, reduce obvious heat of smoke and the water vapour condensation of emitting by temperature in the recovered flue gas and emit the latent heat of vaporization, can make boiler improve about 10% on the basis of original thermal efficiency, all have suitable significance to efficiently utilizing high-grade fuel, raising Business Economic Benefit, minimizing discharging.
Horizontal internal combustion condensing multitubular boiler is little with its compact conformation, floor space, transportation simple installation and being celebrated, and also because of its compact conformation, the layout superheater is very difficult even can't arrange in condensing multitubular boiler structure.For the superheated steam boiler of which degree of superheat little (being little overheated), very difficult usefulness maybe can't be used horizontal internal combustion condensing multitubular boiler structure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the fuel oil or the combustion gas condensing steam boiler that provide a kind of superheater to be built in the horizontal tubular boiler front smoke box.
The purpose of this utility model is achieved in that a kind of superheater is built in fuel oil or the combustion gas condensing steam boiler of front smoke box, comprise shell, flue, return combustion chamber, convection bank, front smoke box, superheater, economizer and condenser, described flue, return combustion chamber and convection bank all are arranged in the shell, flue places bottom in the shell, return combustion chamber is arranged at the flue rear side, with the flue intracavity inter-connection, convection bank places the shell internal upper part, front smoke box is arranged at the outer front upper side of shell, the tube side of convection bank is connected with front smoke box and return combustion chamber, economizer and condenser independently are placed on the boiler body top outer, and described superheater is built in the front smoke box.
The beneficial effects of the utility model are:
1, superheater is built in the front smoke box, and superheater is placed in the space that takes full advantage of in the front smoke box, therefore can utilize the original general structure pattern of horizontal tubular boiler to arrange superheater, realizes superheated steam boiler whole Transporting and installation.
2, adopt independent economizer and the condenser of Influences of Structure of Spiral Finned Tube, volume is little, good looking appearance.
3, external economizer, condenser are arranged in the boiler top, without floor space, change easy for installation.
4, in order to prevent cold end corrosion, condenser adopts ND Steel material and anticorrosion of flue duct to process, and has greatly improved service life.
