Description
Technical field:
The present invention relates to a kind of water coal slurry burner.Especially relate to a kind of automatic and separated combusting coal water slurry, oily dual burner.Be suitable for use in medium and small size of safe with on the hot equipment.Belong to the firing equipment annex
Technical field.
Background technology:
Present situation and cool water mixture burning status of equipment that the energy of China and water-coal-slurry are used are oil-poor rich coals, and the cost of fuel-firing gas-firing is high again, at present mainly based on fire coal.And the serious contaminated environment of traditional fire coal, be the science coal, the deep processed product of preparation coal---water-coal-slurry early has been put into country's eight or five brainstorm projects, up to the present, on large-sized station boiler and stove, obtained using more widely, and the equipment of the middle-size and small-size adapted burner that has a large capacity and a wide range use water-coal-slurry be nearly 2 years at the early-stage.It mainly has the following disadvantages:
1, employed coal-water fluid burner belongs to easy structure, can only combusting coal water slurry can not fuel oil, be hand from the truce overall process of lighting a fire, dip in oil drop combustion light oil with the cotton yarn torch, plain type light oil jet pipe is valve switch by hand.
2, air distribution also closes by hand and opens, and air quantity senior general fire is blown out, and deficiency in draught is with over-emitting black exhaust; fire is blown out the back spray bar can not close rapidly, and the light oil that is sprayed onto in the burner hearth evaporates into oil gas immediately, when lighting a fire once more; detonation takes place, and no flame-out protection device does not have automatic forward and backward purging.
3, combusting coal water slurry does not partly have atomizing disk and steady flame tube, and the process that can not atomize fully burning mainly is to fall in the burner hearth to burn, and the length of flame and diameter be control not, easily coking in the stove.
4, in addition, the burning load of this burner can not be with regulating automatically with the load variations of heat, occur under the various unusual and overrun condition at the equipment of configuration burner, hand-operated valve can not cut out rapidly, overrun condition such as its abnormal conditions and over-temp and over-pressure can not be got rid of rapidly, particularly the hot system of the usefulness that temperature requirement is arranged is had a strong impact on generation and cause the generation of accident, gently then damage main equipment and auxiliary equipment, the heavy then accident that causes casualties.
5, the coal-water slurry nozzle sprayer body adopts overall structure, does not set heat-resistant and wear-resistant material in the spray orifice, causes shower nozzle heat-resistant antifriction and rigidity relatively poor; Water-coal-slurry is directly clashed into the sprayer body inwall, needs the integral replacing shower nozzle, makes that the service life of water-coal-slurry shower nozzle is short.
6,, in " the boilers and pressure vessel manufacturing licence condition " and " rules " of enforcement on January 1 in 2004, over-temp and over-pressure is reported to the police and the interlock protection ignition procedure is controlled and flame-out protection device all explicitly calls for according to No. [2003] 194, state's quality inspection pot literary composition regulation.
