Abstract
The utility model discloses a high-efficiency energy-saving gas fuel boiler furnace structure. The structure comprises a furnace combustion chamber (1) and a combustion device (2). The furnace combustion chamber (1) is divided into an upper conventional furnace (4) and a lower heat insulation furnace (6). The combustion device (2) is disposed on the furnace wall of the lower heat insulation furnace (6). The structure is provided with the heat insulation furnace, i.e., a low heat value gas fuel device is disposed lower than the lower heat insulation furnace. The furnace wall of the upper conventional furnace is a light furnace wall, and the lower heat insulation furnace is a high temperature resistant heavy furnace wall. The furnace bottom is made of a high temperature resistant and fireproof structure. A front wall is added to carry out reconstruction, so that a flame combustion area is enlarged, heat energy is fully used, and furnace space is effectively utilized. The structure is compact in structure. Utilization rate of the device is improved, production cost is reduced, and enterprise economic benefits are raised.
Description
Technical field
The utility model belongs to mechanical equipment technical field, further belongs to boiler plant technical field, be specifically related to a kind of simple in structure, the energy-efficient gaseous fuel boiler furnace structure that heat utilization rate is high.
Background technology
Low calorific value gas fuel boiler of the prior art is in order to make low calorie fuels abundant, conflagration in boiler furnace, general fuel burner region in Boiler Furnace adopts the form of laying wall with refractory lining, refracto or heat accumulation tower being set to arrange the combustion zone of boiler furnace, to improve boiler combustion zone furnace bore temperature, adapt to the burning of low calorie fuels.But the burner hearth arrangement form of the above-mentioned type exists at the bottom of Boiler Furnace conventionally to the low problem of boiler space availability ratio, cause the waste of boiler bottom space and burner arrangement position higher, and easily cause that burning is insufficient, utilization rate of heat value is low, particularly now mostly factory has more with furnace hopper or the higher old boiler of boiler hearth level, while carrying out being suitable for the transformation of low calorific value gas fuel boiler with this type of boiler furnace arrangement form, cause the shortcomings such as construction, improvement project amount is large, investment is high.For this reason, develop a kind of boiler improvement that facilitates, investment cost is low, and the energy-efficient gaseous fuel boiler furnace structure that the thermal efficiency is high is the effective way addressing this problem.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and is convenient to transformation, high usage and cheaply energy-efficient gaseous fuel boiler furnace structure.
The purpose of this utility model is achieved in that and comprises that fire box and burner, described fire box are divided into the conventional burner hearth in top and Adiabatic furnace, and described burner is arranged on the furnace wall of Adiabatic furnace.
The utility model adopts the adiabatic furnace mode that arranges, be about to low calorific value gas fuel device low level and be arranged at Adiabatic furnace, the conventional burner hearth furnace wall in top is set to light boiler setting, Adiabatic furnace furnace wall is resistant to elevated temperatures heavy boiler setting, burner hearth furnace bottom is high temperature resistant fireproof construction, and adopts front wall collocation mode of entrance to transform, and expands the combustion zone of flame, utilize fully heat energy, and effectively utilized furnace space.The utility model compact conformation, has improved the utilization rate of equipment, reduces production costs, and has improved Business Economic Benefit.
Accompanying drawing explanation
Fig. 1 is the utility model whole interior structure cut-away view;
In figure: 1-fire box, 2-burner, 3-water cooled furnace wall, the conventional burner hearth in 4-top, 5-lower header, 6-Adiabatic furnace, 7-burner hearth furnace bottom.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but must not to the utility model, be limited by any way, any change or the improvement based on the utility model training centre, done, all belong to protection domain of the present utility model.
As shown in Figure 1, the utility model comprises fire box 1 and burner 2, and described fire box 1 is divided into the conventional burner hearth 4 in top and Adiabatic furnace 6, and described burner 2 is arranged on Adiabatic furnace 6.
The furnace wall of described Adiabatic furnace 6 is resistant to elevated temperatures heavy boiler setting.
Described burner 2 arranges for front wall setting, both walls liquidate and quadrangle tangential circle arranges a kind of in form.
Described burner 2 is arranged on the furnace wall of Adiabatic furnace 6.
Described burner 2 is gas combustion apparatus.
Described burner 2 is provided with automatic ignition device, repid cut-off valve, the every interlock protection of flame monitoring system (FSSS).
Described burner hearth furnace bottom 7 is high temperature resistant, fireproof construction.
the utility model operation principle and the course of work:
The utility model adopts whole furnace binding, and low calorific value gas fuel device low level is arranged to fire box bottom, has effectively improved the utilization rate of body of heater, has effectively expanded the burner interval of fuel, has improved the utilization rate of heat energy.
When transformation work, remove layout heating surface in burner hearth (as boiler water wall etc.), boiler furnace is divided into two parts, i.e. the conventional burner hearth of upper furnace and Adiabatic furnace.Layout heating surface in upper furnace (as boiler water wall etc.), furnace wall adopts light boiler setting; Lower furnace is as boiler oil combustion zone, and this its furnace wall is resistant to elevated temperatures heavy boiler setting, simultaneously by the burner arrangement of boiler on the position of Adiabatic furnace.In the stove of the conventional burner hearth in top, arrange water-cooling wall, the four sides furnace wall of the conventional burner hearth from top of the water screen tube in stove is through walls and go out and be connected with boiler water wall lower header; Four side furnace walls of Adiabatic furnace are resistant to elevated temperatures heavy boiler setting, and burner hearth furnace bottom is laid with high temperature resistant refractory material; Boiler-burner is arranged on the furnace wall of Adiabatic furnace, can adopt front wall collocation, both walls to liquidate to arrange and the form such as quadrangle tangential circle layout.In this technology, the conventional furnace height in top, the height of Adiabatic furnace, the layout height of the quantity of burner and burner are determined by the size of boiler design rated load and combustion fuel amount.This technology is specially adapted to furnace hopper or the higher old fire coal of boiler hearth level, the adaptability reform that gas fired-boiler carries out fuel gas with low heat value boiler.In transformation process, only need to remove furnace hopper or the furnace bottom of old boiler, then removing the Adiabatic furnace of partly arranging suitable space, under less improvement project amount and lower investment for trnasforming urban land, can realize the raising that uses normal operation and boiler thermal output under low calorie fuels operating mode, combustion stability.Certainly this technology is also applicable to completely newly build the type of furnace layout of boiler.Current this scheme is successfully applied to elder brother's steel 1#75t/h coal-burning boiler and carries out in Blast Furnace Gas-fired Boiler transformation, by lower transformation input, after transformation, boiler has been realized the normal full load operation of fully burning blast-furnace gas operating mode, and boiler thermal output and combustion stability are significantly improved simultaneously.
