WASTE-GAS HEATER-ASH TRAP

摘要

FIELD: physics. ^ SUBSTANCE: proposed waste-gas heater-ash trap comprises external tubes coated by heat insulation and internal tube made up of coil, hot fume gas inlet and outlet branch pipes and cold and hot water inlet and outlet branch pipes. Vertical and central horizontal sections of internal tube are provided with gastight semi-cylinders made from, for example, heatproof metal screen filled with acceptor material. Said cold and hot water inlet and outlet branch pipes are attached to external tube walls at 90 to hot fume gas flow and connected with internal tube coil. ^ EFFECT: better ash collection and expanded performances. ^ 2 dwg
