Abstract
The utility model relates to a coal-block front arch for a boiler with coal tossing machine, comprising a coal covering arch section (1) and a flame refracting arch section (2). The coal-block front arch for a boiler with coal tossing machine can greatly reduce dust emission of the boiler and essentially eliminate black smoke under the condition of not influencing the uniform broadcast of coal. The utility model has the advantages of high thermal efficiency, simple structure, less investment, simple repair, and convenient operation.
Description
Belong to the spreader stoker boliler parts.
Spreader stoker boliler has the coal wide accommodation, and load adaptability is waited outstanding advantage, rather usefulness that some factory and enterprises are found pleasure in well.But this boiler exists critical defects such as chimney over-emitting black exhaust, the discharging dust is many, the flying dust heat loss is big.Generally only adopt secondary wind to eliminate smoke so far and subtract dirt.Yet secondary wind effect in this respect is not satisfactory, and energy consumption is big, cost of equipment is high, noise is big.Therefore spreader stoker boliler is in China's limit production.At present more domestic users adopt two-stage dust removal, and the second level is water film dedusting, but smoke effect still can not meet the demands, and often must bear appreciable fine in the same old way.In addition, also there are problems such as secondary pollution or acid corrosion in wet dust removal, and its initial cost is also than higher.Aspect minimizing flying dust heat loss, all adopt flying dust to reclaim the method for combustion more so far, but its effect is not good yet, and the wearing and tearing of pneumatic ash conveying plant are more serious.
The purpose of this utility model is that a kind of spreader stoker boliler simple in structure of invention hides the coal face arch, to overcome above-mentioned shortcoming.
Main points of the present utility model are to hide the coal face arch to form by hiding coal arch section and arch nose section.It is installed in the top (as shown in Figure 2) of burner hearth front wall, spreader feeder outlet.Hide coal arch section and be mainly used to prevent that duff and the volatile matter Jing that makes progress from flying nonstop to out burner hearth, the arch nose section then further makes them enter after-flame in the thermal-flame.The arch nose section can be downward-sloping.Hide coal arch section and can be horizontal arc, the arch nose section can be downward-sloping arc.The connection of the two can be arc-shaped transition or simple handing-over.Whole screening coal face arch can be bearing on the burner hearth both walls.
The utility model does not influence evenly broadcasts coal, can reduce the boiler dust-exhausting quantity greatly, eliminates chimney over-emitting black exhaust phenomenon substantially, can improve boiler thermal output, simple in structure, small investment, and operation is convenient, and is easy to maintenance.For spreader stoker chain boiler, can also improve the ignition zone furnace temperature, promote to catch fire.
Fig. 1 has provided a kind of embodiment of the present utility model.Wherein 1 is to hide coal arch section, the 2nd, arch nose section.
Fig. 2 is the utility model scheme of installation in spreader stoker boliler.Wherein 3 is spreader feeders, the 4th, and fire grate, the 5th, burner hearth, the 6th, air compartment, the 7th, burner hearth front wall.
Claims (3)
1, a kind of spreader stoker boliler hides the coal face arch, and coal encircles section (1) and arch nose section (2) is formed by hiding to it is characterized in that it.
2,, it is characterized in that arch nose section (2) is downward-sloping as the said screening coal of claim 1 face arch.
3, as the said screening coal of claim 2 face arch, it is characterized in that hiding coal arch section (1) and be horizontal arc, arch nose section (2) is downward-sloping arc.
