Description
Technical field
The utility model relates to a kind of horizontal normal-pressure hot-water boiler.
Background technology
Existing horizontal normal-pressure hot-water boiler is owing to deficiency in draught, and it is insufficient to burn, and the thermal efficiency is low, and the dust concentration of discharging is higher.
Summary of the invention
In order to overcome the existing horizontal normal-pressure hot-water boiler low deficiency of insufficient thermal efficiency of burning, the utility model provides a kind of sufficient combustion thermal efficiency higher horizontal normal-pressure hot-water boiler.
The technical solution of the utility model is to add secondary air channel and secondary tuyere around the burner hearth of existing horizontal normal-pressure hot-water boiler and the smokestack between the secondary furnace, joins an amount of secondary wind when burning, increases combustion efficiency.
This horizontal normal-pressure hot-water boiler comprises shell, flue, fire grate, burner hearth, chimney arch, secondary furnace, convection pass, flue is installed in the shell, logical air pipe is arranged at the top of shell, before the flue, after, both sides, have between the latter half of and shell at the bottom of flue top and the flue and form the hydrospace at interval, secondary furnace, chimney arch, burner hearth and fire grate are successively set on the front portion in the flue from top to bottom, wall with refractory lining, refracto is arranged around the burner hearth, convection pass is arranged on the rear portion of flue, chimney arch has smokestack burner hearth and secondary furnace UNICOM, the front portion of burner hearth is a fire door, the rear portion of secondary furnace communicates with the front portion of convection pass, in convection pass, laterally be installed with some on water spacer and following water spacer, last water spacer is alternate successively with following water spacer, form S shape flue, there is floss hole at the rear portion of convection pass, it is characterized in that: the secondary air channel that annular is being set on every side of smokestack in chimney arch, some secondary tuyeres that communicate with secondary air channel evenly are being set around secondary air channel, secondary tuyere is tilted to and reaches the smokestack inboard, secondary air channel is connecting secondary wind inleting tube, one end of secondary wind inleting tube communicates with secondary air channel, and the other end reaches outside the shell.
When existing horizontal normal-pressure hot-water boiler moves, coal added in the burner hearth burn, the new coal that adds in the burner hearth will at high temperature carry out the dry distillation drying and separate out a large amount of flue gas of fugitive constituent generation, the combustible component of these exhaust gas volumns can not get fully burning and entered atmosphere formation severe contamination owing to the deficiency of air capacity this moment.Because the utility model is provided with secondary air channel and secondary tuyere around the smokestack in chimney arch, under the effect of air-introduced machine, spray secondary hot-air, increase the air quantity of secondary furnace, the fugitive constituent that coal is separated out when dry distillation, drying can be fully burned, and has improved the thermal efficiency.Flue gas carries out heat convection through convection heating surface after entering secondary furnace by the smokestack of chimney arch more then, at last by flue outlet, air-introduced machine, enters atmosphere through smokestack.The thorough like this boiler over-emitting black exhaust phenomenon of having eliminated has reached and has eliminated cigarette, flue dust, energy-conservation effect.
