Abstract
The utility model relates to a steam boiler for burning low calorific value fuel gas, and the steam boiler for burning low calorific value fuel gas includes a furnace body and a furnace hearth arranged in the furnace body. Heat transfer oil heating coil component is arranged in the furnace hearth, and is rolled from inside to outside by the heat transfer oil heating coil. A flue gas outlet is opened on the lateral side of the upper portion of the furnace body, a burner is arranged at the top of the furnace body, and the burner is provided with a flue gas inlet. The lower end of the burner is communicated into the furnace hearth, and the interval between adjacent circles of the heat transfer oil heating coil is 1/4 to 1/3 of the pipe diameter of the heat transfer oil heating coil. The steam boiler for burning low calorific value fuel gas aims at a low heat value gas, utilizes a burner with a heat storage structure, a three-stage ignition and the like to guarantee that the intaken air can be in a normal combustion under a certain fluctuation. In addition, the steam boiler for burning low calorific value fuel gas increases the clearance between coils both inside and outside circle, solves the problems that the low calorific value gas combustion produces a large number of flue gas, and guarantees the normal combustion and good heat transfer effect.
Description
Technical field
The utility model relates to the steam boiler technical field, especially a kind of steam boiler of lower heat of combustion fuel gas.
Background technology
Under the main trend of energy-saving and emission-reduction, a lot of nonstandard sources of the gas of domestic appearance, conventional gas, the calorific value of liquefied gas be the 8000-10000 kilocalorie/cube, some low-calorie sources of the gas comprise coke-stove gas, dry gas, it is low that blast furnace gases etc., calorific value have height to have, and the calorific value of part blast furnace gas only has 1/10th of common natural gas, namely the 800-1000 kilocalorie/cube about, and there is the nonstandard gas of part to have corrosivity, contains sulfur dioxide, the corrosivity compositions such as hydrogen sulfide.It is large that fuel gas with low heat value has air inflow, the intake valve group is thick, and fuel air is unstable, and admission pressure is unstable, the unfavorable factors such as corrosivity, low-calorie fuel gas can not directly burn, and fuel mixes with exotic fuels gas at most as a supplement, more situation is that directly waste is emptying, like this certainly will be to environment, on the other hand, a large amount of flue gas heat also will be wasted.
The utility model content
The technical problems to be solved in the utility model is: can not as the technical problem of gas source, provide a kind of steam boiler of lower heat of combustion fuel gas in order to solve prior art medium and low heat value fuel gas.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of steam boiler of lower heat of combustion fuel gas, comprise body of heater and be arranged on the interior burner hearth of body of heater, be provided with the heat-conducting oil heating coil pack in the described burner hearth, described heat-conducting oil heating coil pack is formed by the heat-conducting oil heating coil pipe system of enclosing from inside to outside, described upper of furnace body side has exhanst gas outlet, the body of heater top is provided with burner, has smoke inlet on the described burner, the burner below is communicated in the burner hearth, and the spacing between described adjacent every circle heat-conducting oil heating coil pipe is 1/4 ~ 1/3 of heat-conducting oil heating coil pipe caliber.
Further, the spacing between described adjacent every circle heat-conducting oil heating coil pipe is 1/4 of heat-conducting oil heating coil pipe caliber.
The beneficial effects of the utility model are, the utility model adopts the burner of accumulation of heat structure for fuel gas with low heat value, and three grades of modes such as igniting guarantee air inlet normal combustion in fluctuation situation necessarily; In addition, increase Internal and external cycle coil pipe gap, solved the problem that low-calorie fuel gas buring produces a large amount of flue gases, guarantee the heat-transfer effect that normal burning is become reconciled.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the steam boiler of lower heat of combustion fuel gas of the present utility model.
Among the figure: 1. body of heater, 2. burner hearth, 3. heat-conducting oil heating coil pack, 31. heat-conducting oil heating coil pipe, 4. burners.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
With reference to figure 1, the utility model comprises body of heater 1 and the burner hearth 2 that is arranged in the body of heater 1, be provided with heat-conducting oil heating coil pack 3 in the burner hearth 2, heat-conducting oil heating coil pack 3 is formed by many heat-conducting oil heating coil pipes 31 system of from inside to outside enclosing, body of heater 1 upper side has exhanst gas outlet, and body of heater 1 top is provided with burner 4, has smoke inlet on the burner 4, burner 4 belows are communicated in the burner hearth 2, and the spacing between adjacent every circle heat-conducting oil heating coil pipe 31 is 1/4 of heat-conducting oil heating coil pipe 31 calibers.The utility model adopts 4, three grades of modes such as igniting of burner of accumulation of heat structure to guarantee air inlet normal combustion in certain fluctuation situation for fuel gas with low heat value; In addition, increase Internal and external cycle coil pipe gap, solved the problem that low-calorie fuel gas buring produces a large amount of flue gases, guarantee the heat-transfer effect that normal burning is become reconciled.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
