Abstract
A new-style fire-box structure for horizontal boilers comprises a circular cylinder, a front blocking plate and a fire tube. The front blocking plate is arranged at the front end of the circular cylindrical and the one end of the fire tube passes through and presses against the front blocking plate. The other end of the fire tube protrudes from the back end of the circular cylinder and a water interlayer is formed by the circular cylinder and the fire tube. Whirl plates are arranged in the fire tube. According to this arrangement, the residence time of fumes in the fire tube is prolonged so that the efficiency of heat utilization is improved to achieve a high practical value.
Description
Technical field
The utility model belongs to boiler manufacturing technology field, is specifically related to the new-type fiery barrel structure for horizontal boiler.
Background technology
Current existing boiler, fire cylinder in its combustion chamber consists of annular canister, front apron, backboard and fire tube conventionally, front apron and backboard divide and are located at annular canister inner chamber two ends, fire tube two ends are supported on respectively on front apron and backboard and with annular canister and form water interlayer, although this kind of structure can be burnt heat by water, but because the holdup time of flue gas in fire tube is too short, cause boiler to have that air consumption is large, the defect insufficient and that the thermal efficiency is low of burning, be therefore necessary to improve.
Utility model content
The technical problem that the utility model solves: a kind of new-type fiery barrel structure for horizontal boiler is provided, in the fire tube of fire cylinder, spinning disk is set, the flow velocity of reducing smoke in fire tube, increases the holdup time of flue gas in fire tube, effectively improves the heat utilization efficiency of boiler.
The technical solution adopted in the utility model: for the new-type fiery barrel structure of horizontal boiler, there is annular canister, front apron and fire tube, described front apron is located at annular canister inner chamber front end, described fire tube one end is passed and is supported on front apron, the fire tube other end stretches out annular canister rearward end and forms water interlayer with annular canister, in described fire tube, is provided with spinning disk.
Further, described spinning disk is sheet metal and is twisted into twisted shape.
Further, described spinning disk adopts stainless steel to make.
The utility model, compared with prior art by spinning disk is set in fire tube, increases the holdup time of flue gas in fire tube, thereby improves the heat utilization efficiency of boiler, has higher practical value.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1,2, a kind of embodiment of the present utility model is described.
New-type fiery barrel structure for horizontal boiler, there is annular canister 1, front apron 2 and fire tube 4, described front apron 2 is located at annular canister 1 inner chamber front end, described fire tube 4 one end are passed and are supported on front apron 2, fire tube 4 other ends stretch out annular canister 1 rearward end and form water interlayer with annular canister 1, in described fire tube 4, be provided with spinning disk 3, spinning disk 3 is for sheet metal and be twisted into twisted shape, preferentially adopts stainless steel to make.
When high-temperature flue gas enters from fire tube 4 front ends, existence due to spinning disk 3, high-temperature flue gas is passed through slowly in fire tube, virtually make the flow process of high-temperature flue gas in fire tube 4 increase, after being fully used, the heat of high-temperature flue gas discharges again, thereby increase heating surface area, the heat utilization efficiency of raising boiler.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
