Abstract

Various schematic circuits for thermal protection of the gas outlet tract and chimney of gas-fired boiler plants from possible condensate formation are proposed. The technology principle consists in combining the cooling of waste gases in water heating heat-recovery equipment with the subsequent increase in their temperature due to: partial bypass of waste gases past the heat-recovery device, mixing of dry hot air or heating in gas heaters.
