Abstract:

The article considers the questions of improvement of combustion processes in natural gas hearth burners with the transfer of boilers from solid fuel to natural gas. A device and a hearth burner. Describes the process of combustion of natural gas in the hearth burners. In this paper, the results of the study of improving the combustion efficiency (reducing losses from chemical underburning and reducing the coefficient of excess air) of natural gas in the furnace of the boiler DK-4-13 of the heating boiler company for the production of concrete products in the Vologda region, translated from the burning of solid fuel, the hearth burners equipped, in terms of open and closed burner embrasures.

Keywords:
