Gas-fired direct contact water heater

摘要

The heater, designed to produce hot water for domestic and industrial use, consists of a first housing (10) containing a water sprinkler (15) and a heat exchanger (17) connected to a burner (18) fed with a combustible gas. The lower end of the housing has a water collector (20). The heater incorporates additional housings (21,30) with water sprinklers and heat exchangers, connected to the first housing by ducts (23,33). The duct is connected to the first housing via the gas burner and provides moist air for mixing with the combustible gas.
