EVALUATION OF TECHNICAL MEANS OF PROTECTION OF AIR THERMAL PLANTS
In the engineering industry the development of a significant role is played by thermal workshops, providing high mechanical, physical and chemical properties of the metal. In the process of the technological process of heat treatment in the air of the working area gets a large number of hazards that can under certain circumstances cause variations in health status or proof of occupational diseases. The most important technical measures aimed at protecting workers, is the selection of reliable means of collective protection. For more effective removal of harmful substances from the mine furnaces proposed replacing the hood a more efficient form of local ventilation – suction ring. The calculation of the suction ring on the example of mine carburizing furnace. It is shown that the use of local exhaust ventilation at the mine carburizing furnaces in the form of a ring instead of suction hood will ensure reliable functioning and sophisticated production equipment, as well as create conditions for a safe and friendly service to all units and personnel systems in the enterprise.
