Abstract
The utility model provides a water coal slurry boiler burner. The utility model is characterized in that the front end of the utility model is provided with rotational flow wind chamber and a refluxing blunt body which is favorable to the stable combustion of the water coal slurry, and a barrel-shaped water coal slurry burning chamber with an inner layer and an outer layer, which is composed of a steel plate and refractory material, is arranged on the rear part of the utility model. The combustion supporting air for the water coal slurry induced from a blower is blown in an interlayer. In addition, the rotational flow wind chamber is provided with an igniting hole and an observation hole, and the burning chamber is provided with a hand hole. The water coal slurry boiler burner with the structure effectively solves the problem that the burner is forced to stop combustion owing to reasons of dust deposition, slag formation, etc. The utility model has the characteristics of compact structure, reliable operation, fast ignition and starting, easy control and high combustion efficiency. The utility model can meet the continuous running requirements of industrial and mining enterprises and civil heating.
Description
Technical field:
It is industry or the civilian steam or the hot water apparatus of fuel that the utility model belongs to water-coal-slurry or mud coal slurry.
Background technology:
Water-coal-slurry is a kind of novel coal based fluid fuel, has the pipeline transportation of being easy to, be convenient to loading and unloading, storage and oligosaprobic characteristics, the coal-water fluid burner that the researcher has developed multiple pattern uses water-coal-slurry, wherein be mostly large-scale be to use on the device of fuel with the coal dust, at the water-coal-slurry device that industry and civil area are used, also do not have a kind ofly can satisfy continuous service requirement, what wherein mainly need solution is the problem of ash disposal and slagging-off.
Summary of the invention:
The purpose of this utility model is the burner that a kind of water-coal-slurry or mud coal slurry will be provided, so that problems such as the dust stratification of solving device, slagging scorification effectively.
The technical solution of the utility model realizes by following manner: this device be a kind of be the burner of fuel with water-coal-slurry or mud coal slurry, it is characterized in that being furnished with the eddy flow air compartment and being beneficial to the backflow bluff body of water-coal-slurry smooth combustion at this device front end.The eddy flow air compartment is circular, and the air channel inlet is along tangentially entering on the circumferencial direction of eddy flow air compartment, forces rotation after the wind of being introduced by pressure fan enters this air compartment, thereby forms the eddy flow wind that is beneficial to the hot flue gas of backrush; The backflow bluff body is a taper shape, makes of steel plate or other materials, connects a sleeve pipe at the top of circular cone, and the water-coal-slurry rifle inserts in the combustion chamber by this root sleeve pipe; Observe and igniting for convenient, also have fire hole and peep hole at the eddy flow air compartment.Combustion chamber is made up of inner core and urceolus, and inside and outside tube all can be made of steel plate.Inboard at inner core has refractory material, and thermal-flame that forms behind the cool water mixture burning and flue gas pass inner chamber body with higher effluxvelocity, and its effluxvelocity is not less than 12m/s usually, thereby plays the purpose that prevents dust stratification and slagging scorification; For cooling off inner core and making water-coal-slurry completing combustion, this device also is provided with urceolus, and the interlayer between the inner/outer tube forms an annular wind, can play the purpose of cooling inner core, annular wind can be heated again simultaneously, thereby make annular wind play combustion-supporting effect; For convenient case of fire and the handling failure of observing, on combustion chamber, also be provided with hand hole.
Description of drawings:
Fig. 1 is the structural representation according to water-coal-slurry provided by the utility model or mud coal slurry burner.
The specific embodiment:
In order further to disclose the technical solution of the utility model, also be further elaborated in conjunction with the embodiments below by accompanying drawing.
As Fig. 1, this device mainly by eddy flow air compartment 1, slurry holster pipe 2, peep hole 3, fire hole 4, surely fire bluff body 5, water-coal-slurry and surely fire inner chamber 6, urceolus 7, hand hole 8 constitutes.Eddy flow air compartment 1 is circular, and the air channel inlet is along tangentially entering on the circumferencial direction of eddy flow air compartment, forces rotation after the wind of being introduced by pressure fan enters this air compartment, thereby forms the eddy flow wind that is beneficial to the hot flue gas of backrush; Backflow bluff body 5 is taper shapes, makes of steel plate or other materials, connects a sleeve pipe 2 at the top of circular cone, and the water-coal-slurry rifle inserts in the combustion chamber by this root sleeve pipe 2; Observe and igniting for convenient, also have fire hole 4 and peep hole 3 at the eddy flow air compartment.Combustion chamber is made up of inner core 6 and urceolus 7, and inside and outside tube all can be made of steel plate.Inboard at inner core has refractory material, and thermal-flame that forms behind the cool water mixture burning and flue gas pass inner chamber body with higher effluxvelocity, and its effluxvelocity is not less than 12m/s usually, thereby plays the purpose that prevents dust stratification and slagging scorification; For cooling off inner core and making water-coal-slurry completing combustion, this device also is provided with urceolus, and the interlayer between the inner/outer tube forms an annular wind, can play the purpose of cooling inner core, annular wind can be heated again simultaneously, thereby make annular wind play combustion-supporting effect; For convenient case of fire and the handling failure of observing, on combustion chamber, also be provided with hand hole 8.At first with fuel oil or natural gas fired, the water-coal-slurry of burning usefulness enters after the slurry rifle carries out the secondary atomizing carries out one-level and fire burns in the stable burning cavity, with fuel oil or after natural gas multifuel combustion a period of time, can realize the independent burning of water-coal-slurry.Go out water-coal-slurry thermal-flame behind the stable burning cavity and hot flue gas at a time when the timely benefit of annular hot blast is gone into, realized the secondary firing process of water-coal-slurry.Hot flue gas after the burning carries the part soot particle and enters in the equipment such as boiler and burn and heat exchange, thereby finishes the combustion process of whole water-coal-slurry.
This burner is to design on by the basis of optimizing, improving oil burning installation integral layout and structure, and it has solved the device that causes owing to reasons such as the dust stratification of device, slagging scorification effectively and has been forced to the stoppage in transit problem.The water-coal-slurry of this kind structure or mud coal slurry burner have compact conformation, reliable, ignition trigger fast, be easy to control and characteristics that efficiency of combustion is high, can satisfy industries such as industrial and mining enterprises and the civil heating demand of operation continuously.
