Abstract
A carbon monoxide (CO) boiler or steam generator having a water cooled CO boiler floor with screen gas distribution inlet to enhance distribution of CO gas in a CO boiler. Either the front or rear wall tubes of the steam generator form an integral screen and the tubes continue, forming a membraned, gas tight enclosure. The floor has a “knee” to redirect the incoming waste CO gas up into the integral screen. The screen may be provided with tube erosion shields to prevent erosion of the screen tubes and to control the distribution of waste gas across the plan area of the furnace.
Claims21
A carbon monoxide (CO) boiler, comprising:
- a furnace enclosure having front, rear and side walls made of membraned tubes;
- a CO gas conduit for conveying CO gas into the furnace enclosure;
- a water cooled CO boiler floor with screen gas distribution inlet, the floor made of tubes forming a front wall of the furnace enclosure separated from one another and without membrane therebetween to form an integral screen provided with an arrangement of gaps or apertures between adjacent tubes for conveying CO gas therethrough into the furnace enclosure;
- and
- a knee formed of membraned furnace enclosure tubes made of tubes forming a front wall of the furnace enclosure for redirecting incoming CO gas upwardly through the water cooled CO boiler floor with screen gas distribution inlet into the furnace enclosure.
