Existing reformation square chest burner normally adopts nature air feed form, and surrounding air enters burner under combustion chamber draft, with fuel mixed combustion in fire trough.Because the temperature of combustion air is low, pressure is low, has caused the chemistry of fuel incomplete combustion loss bigger, system's efficiency of utilization is low.How effectively utilizing refinery's low parameter working medium waste heat and improve efficiency of combustion, reach the purpose of bi-directional energy-saving, is emphasis meaning of the present utility model.
Summary of the invention
The purpose of this utility model proposes a kind of self-preheating natural ventilation burner burning on side of reforming square chest furnace, makes it have energy-saving and environmental protection, characteristics of high efficiency.
The purpose of this utility model can adopt following technical scheme to realize:
A kind of self-preheating natural ventilation burner burning on side of reforming square chest furnace, at the burner body front end a preposition air heat exchanger is set, described preposition air heat exchanger has the heat exchanger channels with the air inversion heat exchange, have the many rows working medium coil pipe with the air heat exchange in the described heat exchanger channels, the two ends of working medium coil pipe have chamber and are communicated with chamber respectively; Two chambers are provided with inlet tube, the outlet that is communicated with working medium, at the center of many row's working medium coil pipes gas gun are set, and promptly the gas gun of burner passes the center of many row's working medium coil pipes; The heat exchanger channels of described preposition air heat exchanger is communicated with burner body by connecting pipe, promptly be communicated with the fire trough of burner by heat exchanger channels, preposition air heat exchanger is communicated with burner body by connecting pipe, combustion air is under the effect of combustion chamber draft, enter preposition air heat exchanger, make the working medium of air and low parameter in preposition air heat exchanger, carry out countercurrent flow, hot-air after the heat exchange enters in the burner body by connecting pipe, the fuel smooth combustion in burner that sprays by stable flame cover and gas gun again under the adjusting of transferring wind mechanism.
Described a kind of self-preheating natural ventilation burner burning on side of reforming square chest furnace, described working medium can be steam, water, the wet goods working medium waste heat of low parameter.
The utility model and conventional natural ventication burner relatively have the following advantages:
1) improve also overheavy firing, after entering in the stove through the hot-air after the preheating, combustion air has certain temperature, quickened fuel drying, catch fire and combustion process, guarantee smooth combustion in the stove, play a part improvement, overheavy firing, improved efficiency of combustion; 2) augmentation of heat transfer adds that the hot blast temperature that enters in the stove improves because the stove internal combustion improves and strengthens, and the mean temperature level also has raising in the stove, thereby can strengthen radiant heat transfer in the stove.Improved the radiant heat utilization ratio; 3) reduce the stove internal loss, reduce steam, water, the loss of wet goods working medium waste heat of low parameter, because the stove internal combustion is stable, the reinforcement of radiant heat exchange can reduce loss of the inadequacy burning for chemistry mechanics reason.On the other hand, preposition air heat exchanger utilizes the working medium waste heat, has further reduced the hot working fluid loss, therefore, has improved burner hearth efficient and whole system recuperation of heat utilization ratio; 4) utilize steam, water, the wet goods waste heat of low parameter to heat combustion air, avoided the thermal pollution that is lost in the atmosphere to be caused because of the working medium waste heat, therefore, played the effect of environmental protection; 5) fuel saving.Rule of thumb calculate, the utility model and conventional natural ventication burner compare, 40 ℃ of combustion air temperature preheatings. and capable of saving fuel about 1.6%.
