Abstract
The utility model relates to a kind of air distribution plate center air-supply arrangement for CFBB.Current CFBB adopts two Lateral supply, because fluid exists Static compression performance, can cause First air maldistribution before air distribution plate, and then affect the thermo parameters method of burner hearth, affect the efficiency of combustion in stove.The utility model composition comprises: a hot-flow flue (1), a described hot-flow flue is connected with Induct burner (2), described Induct burner is connected with water cooled wind chamber (3), and described water cooled wind chamber is connected with air distribution plate (4), and described air distribution plate is connected with burner hearth (5).The utility model is applied to the center air-supply of CFBB.
Description
technical field:
the utility model relates to a kind of air distribution plate center air-supply arrangement for CFBB.
background technology:
current CFBB adopts two Lateral supply, because fluid exists Static compression performance, can cause First air maldistribution before air distribution plate, and then affect the thermo parameters method of burner hearth, affect the efficiency of combustion in stove.
summary of the invention:
the purpose of this utility model is to provide a kind of air distribution plate center air-supply arrangement for CFBB.
above-mentioned object is realized by following technical scheme:
a kind of air distribution plate center air-supply arrangement for CFBB, its composition comprises: a hot-flow flue, a described hot-flow flue is connected with Induct burner, described Induct burner is connected with water cooled wind chamber, described water cooled wind chamber is connected with air distribution plate, and described air distribution plate is connected with burner hearth.
the beneficial effects of the utility model:
1. the utility model First air is supplied by primary air fan, enter after heating in rotary regenerative air preheater, by a hot-flow flue, through Induct burner, divide at 4 and evenly enter in water cooled wind chamber, water cooled wind chamber is that First air enters air distribution plate prerequisite for an air voltage stabilizing district, be the place of a dynamic and static pressure conversion, be conducive to the uniformity of cloth wind like this, one time hot blast enters in burner hearth by air distribution plate again, ensure the fluidisation of material in burner hearth, and part small particles material is raised up.Owing to enter air compartment on rear side of stove after, there are enough distances that air is flowed along Way in air compartment and all press and current stabilization.
the First air of the utility model CFBB, First air divides evenly feed at 4 from water cooled wind chamber rear, be conducive to making the static pressure distribution in air compartment more even, can effectively avoid air compartment static pressure on the impact of cloth wind uniformity, make boiler cloth wind more evenly, burner hearth flow field and temperature field also more even.Can effectively improve whole unit efficiency, adopt First air air distribution plate center air supply mode, guarantee furnace temperature uniformity, improve efficiency of combustion, strengthen the competitiveness of CFBB.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
detailed description of the invention:
embodiment 1:
a kind of air distribution plate center air-supply arrangement for CFBB, its composition comprises: a hot-flow flue 1, a described hot-flow flue is connected with Induct burner 2, described Induct burner is connected with water cooled wind chamber 3, described water cooled wind chamber is connected with air distribution plate 4, and described air distribution plate is connected with burner hearth 5.
Claims (1)
