Boiler waste heat utilisation system - has pipes of different cross=section welded to tube

摘要

The system makes use of the waste heat from a boiler. It includes a tube to which two pipes of different cross-section are welded one above the other. These two pipes form the feed and return lines to a heating water circuit containing a circulating pump. The feed pipe can be connected to the main circuit via a mixing valve or diversion. Part of the water from the mixing valve or diversion valve goes to the feed and part of it goes into a tank containing a coiled pipe. Water may flow from the tank into the feed.
