MINE CALORIFIER INSTALLATION Russian patent published in 2017 - IPC E21F1/08 E21F3/00 

FIELD: ventilation.

SUBSTANCE: mine calorifier includes blowers, a number of plate elements installed in the lower part of the heater duct adjacent to the shaft of the shaft and oriented along the flow of air. When a water or chemical substance is used as a coolant on the plate elements, a heat exchange tube system is formed that forms a closed loop for the circulation of the heat transfer fluid, including control valves and control devices for supplying the coolant. The plate elements are located in the air passage channel parallel to the walls of the lower part of the heater channel with the possibility of adjusting their angle of inclination relative to each other and the lower part of the heater duct. In this case, the fans are located in the surface building and/or in the air duct to the plate elements and/or after the plate elements.

EFFECT: reduction of energy costs for the operation of the plant with the use of various types of thermal energy and ensuring uniform warming of the air.
