Abstract

FIELD: boiler engineering; boilers working on natural gas or liquid fuels. SUBSTANCE: air heater has U-shaped arrangement with evaporating stage mounted in left-hand branch in way of motion of waste gases; upper head and continuous and periodic blow pipe lines are located above evaporating stage; water-to-air heat exchanger is located in lower portion; this heat exchanger is arranged in volume of condensate receiver provided with cleaning pipe line; condensate receiver connects evaporating stage with lower head and condensing stage located in right-hand branch. Fan located at condensing stage inlet in air end is provided with evaporating and injection pipe lines; fan is also connected to water-to-air heat exchanger and evaporating stage. EFFECT: intensified heat exchange and avoidance of low-temperature corrosion.

Изобретение относится к котельной технике, в которой в качестве топлива используется природный газ или жидкое топливо. Целью изобретения является интенсификация теплообмена и устранение влияния низкотемпературной коррозии. Сущность изобретения заключается в том, что воздухоподогреватель представлен U-образной компоновкой, где в его левой ветви по ходу движения уходящих газов установлена испарительная ступень, над которой расположены верхний насадок и трубопроводы непрерывной и периодической продувок, в нижней части - водовоздушный теплообменник, размещенный в объеме сборника конденсата, имеющего трубопровод очистки, и соединяющий испарительную ступень с находящимися в правой ветви нижним насадком и конденсационной ступенью, на входе в которую по воздушной стороне размещены вентилятор с трубопроводами выпара и впрыска воды, причем последний подключен также к водовоздушному теплообменнику и испарительной ступени.The invention relates to boiler equipment in which natural gas or liquid fuel is used as fuel. The aim of the invention is the intensification of heat transfer and elimination of the influence of low temperature corrosion. The essence of the invention lies in the fact that the air heater is represented by a U-shaped arrangement, where an evaporation stage is installed in its left branch in the direction of the exhaust gases, above which there are upper nozzles and pipelines for continuous and periodic blowing, and in the lower part there is a water-air heat exchanger placed in the volume condensate collector having a purification pipe and connecting the evaporation stage with the lower nozzle located in the right branch and the condensation stage, at the inlet of which by air On the other side there is a fan with evaporator and water injection pipelines, the latter also connected to a water-air heat exchanger and an evaporation stage.
