It is further to exchange heat, change thermogenetic steam and be directly entered drum 6；When temperature is relatively low in heat exchanger, valve c 9, valve is closed
Door d 10, the waste gas in secondary heat exchanger is directly emptied.Pipeline between waste heat boiler and cyclone separator, secondary heat exchanger
On be respectively arranged with blower fan a 11, blower fan b 12.
Above-mentioned specific embodiment is only concrete case of the present utility model, and scope of patent protection of the present utility model includes
But it is not limited to the product form and style of above-mentioned specific embodiment, a kind of any pyrrole for meeting this utility model claims
WHRS and any person of an ordinary skill in the technical field are done to which in pyridine production technology appropriate change or
Modification, should all fall into scope of patent protection of the present utility model.
