The present invention provides an incinerator and fume separator device and a method for burning such materials as refuse, tire chips and sewage sludge or combinations thereof as well as other combustible materials to generate steam to supply steam heat and/or electricity to towns, villages or individual establishments. One of the key features of the system is the use of a horizontal conduit, wherein gases are initially cooled by a water-cooled conduit, part of the particulate material being removed within this tubing by use of baffles and fly ash settling chambers. The gases proceed through this conduit at a relatively high velocity and then through various fume separators located along the conduit by which the gases are intimately mixed with a liquid alkaline solution, such as lime water, by the propelling action of a ribbed slinger or propellor type device, located within the separator which because of its high speed and shearing action produces a cyclonic effect, thereby insuring intimate contact between the acidic contaminants in the gas and the fine droplets of alkaline material. Located underneath the ribbed slinger is a backwardly curved fan to pull the gas-alkaline liquid mixture downward and insure an even more intimate mixing of the contaminated gases and alkaline liquid. The purified gases are then exhausted into the atmosphere. According to the present invention, a variety of trash materials can be incinerated to generate steam and the exhaust gases can be effectively purified.
