Abstract
The heating supply of residential areas in many cities of Ukraine is central. The heat sources of central heating are heating boiler houses with hot water boilers. Heating boiler houses, usually located far from residential areas and heating networks, respectively, have a considerable length. Transportation heat carrier from the heat source to consumers accompanied by loss of heat. It is, according to various sources, is estimated at 10-30 % of the heat energy that released heat source. To reduce heat losses during transportation all heat carrier piping, valves and control valves and other equipment of heating network and boiler houses to insulate necessary. Currently, there are many insulating coatings of pipelines. They are differ by temperature regime of use, material, method of installation, place of use, price. The technical and economic comparison of insulation materials (mineral wool, foamed caoutchouc, polyethylene foam and heat insulating paint) was carried out in the article. The desired thickness insulation material on the value of standardized linear density of heat flow was calculated in technical calculation. Economic calculation consisted in determining the resulted expenses of installation for specified options thermal insulation. Cost-efficient option of thermal insulation for installation on the technological pipelines of boiler house determined by the value of reduced costs of implementing these options. The optimum thermal insulation material for the design of heat supply systems was determined with the value of resulted expenses.
