TH295A3 - Energy saving device with external heat exchanger - Google Patents

Abstract

Energy saving system with external heat exchanger It is a system that increases the water temperature at every point of entry to the energy-saving machine. And steam boilers As well as reducing the temperature of the flue gas at the vapor flue Waste to a temperature higher than the condensation point of every fuel used in the boiler system. To avoid Corrosion to the surface due to Condensation into flue gas concentration In addition to extending life The use of energy saver, flue, boiler, and steam boiler. Also reduce the wastage rate Fuel in the boiler system as well.

Claims (1)

1. Energy saving system with external heat exchanger consists of 1.1 energy saver divided into hot coil. Within the device are two parts 1-2 and 3-4, with the number of internal coils of the two ranges depending on the individual design. 1.2 External heat exchanger is a shell or plate type heat exchanger. The inlet is connected from the storage tank at point 6, the outlet is connected to the energy saver part 1 at point 2, then the energy saver part 1 at point 1 is connected to Exchange machine Change outside heat again Outlet of the external heat exchanger Will be connected to Energy Saver, part 2 at point 3, part 4 of the economizer, continue to connect to the boiler. 1.3 Temperature control device 1.3.1 The temperature probe measures the temperature at the flue at point 5 and sends a contract to the boiler. Temperature control (1.3.2) 1.3.2 Temperature controller is installed at the power cabinet (Control panel) is a transmitter to the three way control valve (1.3.3) 1.3.3 control valve Three way (Three way control valve) receives the signal from the temperature controller to adjust the flow rate of water into the economizer. The flue temperature at point 5 is higher than the dew point of the flue gas.
