DEVICE FOR HEAT RECOVERY Russian patent published in 2013 - IPC F24H1/28 

FIELD: power engineering.

SUBSTANCE: design of a thermal generator for production of thermal energy comprises at least one furnace, in which combustion takes place, one heat exchanger, in which combustion products are cooled, the specified heat exchanger, being a fire-tube boiler, is arranged in one or several smoke contours, comprising many pipes, contained in the outer container of the specified thermal generator, each end of the specified container is equipped with a tube plate for insertion of the specified pipe and the specified furnace, a flue for their discharge into atmosphere. The specified thermal generator is connected by means of a conveyor with one or several thermal sources, which are external thermal sources and are separate from the specified thermal generator and the specified conveyor, transporting hot gases from the specified one or several thermal sources to the specified thermal generator for recovery of enthalpy content. Specified hot gases coming out of one or several heat sources are gaseous combustion products, and also the specified conveyor is adapted to direct the specified gaseous combustion products for transfer of their heat into a part of the specified heat exchanger of the specified thermal generator. The technical result of the invention is also achieved by arrangement of a conveyor for transportation of hot gases from one or several sources of heat into the above thermal generator for enthalpy recovery. The technical result of the invention is achieved by a device for heat recovery, which comprises the above thermal generator and one or several sources of heat, which are connected to each other by a conveyor. The technical result of the invention is achieved by the method of recovery of enthalpy of hot gases coming out of one or several sources of heat in the above thermal generator, in accordance with which they manually select one or several pipes cut by the conveyor and forming a part of the heat exchanger designed for cooling of gaseous combustion products. At the same time physical parameters of gaseous combustion products are mostly stable in course of time and represent, in particular, flow speed and (or) temperature. The technical result of the invention is achieved in the method to recover enthalpy of hot gases coming out of one or several sources of heat, in accordance with which in the above thermal generator they automatically select one or several pipes cut by the conveyor and forming a part of a heat exchanger designed for cooling of gaseous combustion products, by means of an electronic control device, based on change of physical parameters of gaseous combustion products time after time, information about which arrives from the appropriate sensor, which represent, in particular, flow speed and (or) temperature.

EFFECT: development of a simple and cost-effective method and device for heat regeneration.
