System.
Technical background
Currently, domestic mineral hot furnace industry is one of highly energy-consuming major fields, is also one of energy-saving and emission-reduction emphasis, therefore, ore deposit
One of transition and upgrade important channel of hot stove, is the cogeneration technology and efficiency for improving its coal gas and flue gas, realizes mineral hot furnace
Industry energy-conserving and environment-protective and low-carbon (LC) productive target.
The CO produced by reducing agent in mineral heating furnace flue cogeneration thermal source, mainly mineral hot furnace petticoat pipe burns produced
Flue gas, about 650 DEG C of theoretical burning-point, because electrode work done produces more than 2000 DEG C hot reduction reactions in petticoat pipe, in actual petticoat pipe
Ignition temperature is much larger than 650 DEG C.
There is two kinds of techniques and operating mode in mineral heating furnace flue, one is traditional cooling technique is non-UTILIZATION OF VESIDUAL HEAT IN and hair
Electrician's condition, the second is the energy recovery process of thermal-arrest is UTILIZATION OF VESIDUAL HEAT IN and generating operation mode.
Traditional cooling technique is non-UTILIZATION OF VESIDUAL HEAT IN and generating operation mode, will be born in petticoat pipe by environmentally friendly fan action
Pressure about 150pa, make to invade large quantity of air in flue gas, about 350~550 DEG C of flue-gas temperature after mixing, and through surface radiating cool down after,
Make cigarette temperature drop enter sack cleaner to 250 DEG C or so again to discharge.
The energy recovery process of thermal-arrest is UTILIZATION OF VESIDUAL HEAT IN and generating operation mode, is to adjust trend of environmental protection by temperature control interlocking frequency converter
Machine, makes negative pressure about 50pa in petticoat pipe, reduces the air intrusion volume of flue gas, and about 650 DEG C of the cigarette temperature after thermal-arrest is handed over for waste heat boiler heat
After changing, cigarette temperature drop enters sack cleaner and discharges to 150 DEG C or so.
Existing mineral heating furnace flue cogeneration engineering, the energy recovery process for lacking thermal-arrest is UTILIZATION OF VESIDUAL HEAT IN and generating work
Condition recognizes, it is common that on the basis of being non-UTILIZATION OF VESIDUAL HEAT IN and generating operation mode in the scattered hot cooling technique of tradition, using medium and low temperature and
The power generation process with waste heat technology and equipment of pressure, cause existing mineral heating furnace flue cogeneration engineering less efficient and investment is reclaimed
Phase is more long, seriously hampers the development of mineral hot furnace energy-saving and emission-reduction.
