Abstract
A three-air soot blower comprises a barrel, and two nozzles are arranged on the barrel. The three-air soot blower utilizes the technical process of 1.1-1.3 modulated pulse amplifier (MPA) medium-pressure steam soot blowing. Soot attached to a high temperature superheater, a convection tube, an economizer and the like is blew out during the running of a three-air boiler after the decompression of self-produced steam of the three-air boiler, and the aim of long periodic operation of the three-air boiler is achieved. The soot-blowing process is carried out by means of eight groups of automatic devices with each group blowing the soot for 3 to 5 minutes to guarantee the soot in each part is blown out.
Description
Technical field
The utility model relate to a kind of in Ammonia Production the dust purger at the positions such as three gas boiler high temperature superheaters, convection tube, economizer.
Background technology
In the synthetic ammonia generative process, various boiler ammonia synthesis production play vital effect, and particularly three gas boilers utilize waste heat recovery to steam, and substantially realize the Ammonia Production steam self-support, so the heat transfer effect of three gas boilers directly affects steam production.Three gas boilers are in service, easily concentrate on the heat exchanger tube owing to containing a large amount of dusts in the blowing-out gas, and the heat-transfer surface caloric receptivity is reduced, and cause heating surface to import and export flue-gas temperature and raise, and affected the heat exchange efficiency of boiler; Dust stratification stops up air preheater on the other hand increases the subsidiary engine power consumption; In addition, dust stratification also can make the heating surface increase in temperature, causes heating surface tube wall overtemperature and high temperature corrosion even booster.
Summary of the invention
The purpose of this utility model provides a kind of three gas soot blowers that purge for the dust at the positions such as three gas boiler high temperature superheaters, convection tube, economizer.
The purpose of this utility model is achieved in that a kind of three gas soot blowers, comprises gun barrel, and gun barrel is provided with two nozzles.
The utility model the utility model adopts 1.1-1.3MPa middle pressure steam soot blowing technique flow process, the dust that the positions such as high temperature superheater, convection tube, economizer adhere to that three gas boilers are in operation blows out, utilize three gas boiler self-produced steams after decompression, to carry out, reach the purpose of three gas boiler long-term operations.Blow ash and adopt automatics, totally eight groups, every group blowing time 3-5 minute, guarantee that each position obtains blowing ash.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model soot blower.
The specific embodiment
The utility model structure as shown in Figure 1, a kind of three gas soot blowers comprise gun barrel 1, gun barrel 1 is provided with two nozzles 2.
In conjunction with on-the-spot actual, at high temperature superheater and air preheater middle part C304C2500mm type rotary soot blower is installed; C304C4500mm type rotary soot blower is installed at convection section upper, middle and lower position.
C304,4500mm type rake soot blower are installed at economizer upper, middle and lower position.
The utility model the utility model adopts 1.1-1.3MPa middle pressure steam soot blowing technique flow process, the dust that the positions such as high temperature superheater, convection tube, economizer adhere to that three gas boilers are in operation blows out, utilize three gas boiler self-produced steams after decompression, to carry out, reach the purpose of three gas boiler long-term operations.Blow ash and adopt automatics, totally eight groups, every group blowing time 3-5 minute, guarantee that each position obtains blowing ash.
