Abstract
The utility model discloses a kind of hopper burn-out-proof devices to play the role of a kind of protective device for solving the problems, such as that particulate biomass fuel is in combustion burnt out fuel hopper due to thermal-flame.This hopper burn-out-proof device is made of collecting pipe component, high pressure spout, compressed air regulating valve and fixing bracket, wherein collecting pipe component both ends are threaded respectively is equipped with because of fixed rack, high pressure spout is connected and fixed with collecting pipe component, and compressed air regulating valve is fixed on collecting pipe component.This hopper burn-out-proof device has the characteristics that principle is simple, compact-sized, easily manufactured, cheap, convenient to install and maintain, can be widely used on the burner of particulate biomass fuel, and burn-out-proof protective effect is played to fuel hopper.
Description
Technical field
The utility model is related to the hopper burn-out-proof devices on burning boiler in a kind of Thermal Power Engineering application technology, especially relate to
And a kind of particulate biomass fuel prevents a kind of protective device that thermal-flame burns out the hopper that burns in combustion.
Background technology
This technology belongs to Thermal Power Engineering application technology, and according to the characteristic of biomass fuel, the fugitive constituent height of fuel sees fiery point
It is low, the operation of fireman is required during firing biomass fuel very high.Because accidentally thermal-flame can be stood
Quarter ignites hopper, directly affects normal stoker, or even hopper and feed bin are burnt out, and major accident occurs.It is this to prevent
The generation and security consideration of phenomenon, it is necessary to try to design a kind of protective device to fuel hopper.
Invention content
The purpose of this utility model is to provide for a kind of hopper burn-out-proof device, is being burnt with solving particulate biomass fuel
The problem of causing to burn out fuel hopper due to thermal-flame in the process.This hopper burn-out-proof device be by：Collecting pipe component, high pressure
Spout, compressed air regulating valve and fixing bracket composition, wherein collecting pipe component both ends are equipped with by screw joints solid respectively
Fixed rack, high pressure spout are connected and fixed with collecting pipe component, and compressed air regulating valve is fixed on collecting pipe component.
The hopper burn-out-proof device designed and produced according to above-mentioned technical proposal, compared with prior art its notable advantage be：
It is simple with principle, compact-sized, the features such as being simple to manufacture, is cheap, is convenient to install and maintain, it can be widely used in graininess
On the burner of biomass fuel.
Description of the drawings
Fig. 1, hopper burn-out-proof apparatus structure schematic diagram.
The A-A direction views of Fig. 2, Fig. 1.
Fig. 3, the fire grate burner use state diagram for being equipped with hopper burn-out-proof device.
Specific implementation mode
The hopper burn-out-proof device of the utility model, is further described by following accompanying drawings and embodiments：
As shown in Figure 1 and Figure 2：Hopper burn-out-proof device be by collecting pipe component 1, high pressure spout 2, compressed air regulating valve 3 and
Fixing bracket 4 form, wherein 1 both ends of collecting pipe component are threaded respectively is equipped with fixing bracket 4, high pressure spout 2 with
Collecting pipe component 1 is connected and fixed, and compressed air regulating valve 3 is fixed on collecting pipe component, and fixing bracket is positioning gas collection
Tube assembly and be arranged.Hopper burn-out-proof device is located in after hopper, before furnace front baking.The hopper formed according to above structure
Burn-out-proof device is in use, hopper burn-out-proof device before being placed on furnace front baking（As shown in Figure 3：Hopper burn-out-proof device is installed
Fire grate burner use state diagram）, its main feature is that in the case where not influencing combustion conditions, utilize pressure-air
（High-pressure low-flow air）By the high pressure spout to turn forward, injection forms air curtain, the radiant heat in burner hearth is lighted
Fuel flame is blown into burner hearth, while reducing the ignition temperature of fuel, and the ablaze purpose of hopper is prevented to reach.The dress
It sets and is widely used on the burner of particulate biomass fuel, burn-out-proof protective effect is risen to fuel hopper.
