Abstract

FIELD: boiler engineering; boilers working on natural gas and liquid fuel. SUBSTANCE: waste heat recovery has evaporating stage and condensing stage; upper head and continuous and periodic blow water pipe lines are mounted above evaporating stage; fans with vapor and water injection pipe lines are mounted at inlet of condensing stage on air side; fan is also connected to inlet of evaporating stage; they are also connected (in way of flow of waste gases) to left- and right-hand branches of U-shaped arrangement of waste heat recovery which are connected through condensate receiver; besides, they receive tubes finned with common fins which form alternating passages for flow of air and combustion products; outer tubes are used for transportation of air and finned tubes of both branches are connected by means of water-to-water heat exchanger. EFFECT: enhanced efficiency.

Изобретение относится к котельной технике, в которой в качестве топлива используется природный газ и жидкое топливо. Сущность изобретения заключается в том, что над испарительной ступенью водовоздушного утилизатора теплоты установлены верхний насадок и трубопроводы воды непрерывной и периодической продувок, в конденсационной ступени на входе по воздушной стороне размещены вентилятор с трубопроводом выпара и впрыска воды, причем последний подключен также ко входу в испарительную ступень, ступени соответственно подключены по ходу движения уходящих газов к левой и правой ветвям U-образной компоновки утилизатора, которые соединены через сборник конденсата, кроме того, в них размещены трубы, оребренные общими ребрами, которыми образованы чередующиеся каналы для прохода воздуха и продуктов сгорания, причем внешние предназначены для транспортирования воздуха, а оребренные трубы в обеих ветвях связаны посредством водоводяного теплообменника.The invention relates to boiler equipment in which natural gas and liquid fuel are used as fuel. The essence of the invention lies in the fact that an upper nozzle and water pipes of continuous and periodic blowing are installed above the evaporative stage of the water-air heat recovery unit, a fan with a vapor and water injection pipe is placed in the condensation stage at the inlet on the air side, the latter being also connected to the entrance to the evaporative stage , the steps are respectively connected in the direction of the flue gas to the left and right branches of the U-shaped layout of the utilizer, which are connected through the collector nsata, in addition, they are placed pipes finned with common ribs, which are formed by alternating channels for the passage of air and combustion products, the outer ones are designed to transport air, and finned tubes in both branches are connected by means of a water-water heat exchanger.
