FIELD: heating systems. ^ SUBSTANCE: invention refers to agricultural engineering and can be used in grain-drying complexes for drying grains and various seeds of technical crops, as well as for heating cattle farms, industrial automobile garages, etc. Heat generator includes housing made in the form of two cylinders - external and internal ones installed one inside the other. Combustion space of internal cylinder is divided into furnaces. There is blasting fan. Between two cylinders, throughout the length and in circumferential direction of internal cylinder there spirally and parallel to each other located are heat exchange plates; at that, combustion space of internal cylinder is divided into furnaces with partitions in which holes for gas duct are made, and each furnace is equipped with furnace door and blasting door. ^ EFFECT: reducing grain drying prime cost. ^ 4 dwg |
