RAISING ECONOMIC EFFICIENCY OF JACKET TECHNOLOGICAL DEVICES AT THE EXPENSE OF DECREASING METAL-CONSUMING AND POWER-CONSUMING CHARACTERISTICS

The article grounds economic expediency of using jacket thermal exchangers of the sheet-canal type. As a rule steam jackets of technological devices in food industry and catering enterprises have a form of an open slit space and for work under pressure they are made of walls of big thickness, which...
