A heating plant which includes an upstanding housing with a combustion chamber in the lower part of the housing, a high pressure burner extending within the combustion chamber, a flue gas pipe extending upwardly from the combustion chamber to terminate in a smoke trap. The smoke trap is in the form of a dome having a dome skirt extending downwardly below the upper level of the flue gas pipe, and a vessel for maintaining a washing liquid at a predetermined level between the upper limits of the flue gas pipe and the lower edge of the dome skirt. Openings are provided in the dome skirt below the level of the liquid, such that smoke coming from the flue gas pipe is forced to bubble through the washing liquid through the openings in the dome wall and up to a chamber to be exhausted from the housing. Various heat exchanger means are provided in the housing for extracting heat from the combustion chamber and the smoke system.
A heating plant comprising a housing, a combustion chamber, a high pressure burner associated with the combustion chamber, an exhaust pipe extending from the combustion chamber vertically within the housing and terminating within a smoke trap provided in the housing, the smoke trap including a dome having a downwardly extending skirt, the skirt extending below the top level of the exhaust pipe, means for maintaining a smoke washing liquid level below the level of the exhaust pipe and above the bottom edge of the dome skirt within the housing, openings provided in the dome skirt in the area below the liquid level, said openings decreasing in area from the bottom edge of the skirt to the top limit of said openings below the level of the liquid, an exhaust stack communicating with the housing above the dome, and heat exchange means associated with the housing through which heat exchange fluid may be circulated for extracting the heat generated in the heating plant.
