Autonomous heat supply of production buildings, offices and accommodation spaces by contact water-heaters.
Technology and equipment for water heating in contact water-heating modules with heat power 1,0 and 0,5 Gcal/h have been developed. In mentioned modules are combined contact and surfaces methods of water heating. It provides water heating till 90-95 ºC, that is higher than in conventional production methods of hot-water supply. At the expense of latent heat evaporation utilization of water vapour from combustion materials the modules efficiency factor is exceeded 96%. The temperature of combustion materials at the output of modules is 50 –55 ºC.
|The space for modules placing, m2||7х4,0||1,3х1,5|
|The height, m||4,2||2,3|
|Mass of system’s crucial components, kg||1800||950|
The module is equipped by multiflame burner and combustion chamber with heat-exchanges apparatus that is based above the chamber. 1,0 Gcal/h module is capable to heat one office block or residental construction with a space 10t hous.m² and 0,5 Gkal/h module – 5t hous.m². The cost of 1,0 Gkal produced by modules is half than under centralized heating.
