Description
Technical field
The utility model belongs to burner arts, relates to a kind of station boiler spraying burner fire nozzle.
Background technology
Coal dust burns with coal burner under various different combustion type, different condition as boiler oil, the efficiency of combustion of coal dust, the thermal efficiency, reduction power consumption can be improved, reduce air environmental pollution, thermal power plant mainly uses pulverized-coal fired boiler, the burner form used is more, because the space of boiler is large, load large, the power of required coal burner is also large.At present, existing spraying burner fire nozzle complex structure, use inconvenience, Coal powder spray weak effect, cannot meet user demand, therefore have much room for improvement.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides the station boiler spraying burner fire nozzle that a kind of structure is simple, easy to use, Coal powder spray is effective.
The utility model is achieved by the following technical solution:
Station boiler spraying burner fire nozzle of the present utility model, is characterized in that: comprise main cylinder, two points, the left and right cylindrical shell tilting to be connected on main cylinder and the upper shell be connected to above main cylinder; Main cylinder comprises the lower cylindrical drum connected successively from the bottom up, upper cylindrical drum and upper taper cone barrel, the diameter of lower cylindrical drum is greater than cylindrical drum, the contact surface of lower cylindrical drum and upper cylindrical drum is inclined-plane, inclined-plane is provided with connecting plate and lower cylindrical drum and upper cylindrical drum is linked together, diametrically going up of taper cone barrel is shunk gradually, the diameter of the opening at taper cone barrel top is less than the diameter of cylindrical drum, and the opening of taper cone barrel is connected with annular flange dish, and this ring flange connects the annular flange dish bottom upper shell; Conically, upper young, the end opening of upper shell is large, and the tapering of upper shell is 22 ° for upper shell; Point cylindrical shell in left side connects the upper cylindrical drum of main cylinder, point cylindrical shell in left side comprise connect successively from top to bottom ring flange, become large taper cone barrel, cylindrical drum diametrically down, cylindrical drum connects main cylinder; Point cylindrical shell on right side connects the lower cylindrical drum of main cylinder, point cylindrical shell on right side comprise connect successively from top to bottom ring flange, cylindrical drum, become large taper cone barrel diametrically down, taper cone barrel connects main cylinder.
The beneficial effects of the utility model are, structure is simple, easy to use, Coal powder spray is effective, spraying range is wide, spray evenly, the power plant of large, medium and small combusting coal fines, oil, chemical industry, metallurgy, heating furnace, building materials kiln, civil boiler for warming etc. can be adapted to, various ature of coal can be burnt, burn-off rate is high, the thermal efficiency is high, without black smoke not slagging scorification, and can realize in the lower situation of excess air coefficient also can smooth combustion, effectively reduce growing amount and the discharge capacity of harmful substance in burning, useful environmental protection, energy-conservation.
