Hot water heating system expansion tank / compression tank drain procedure to re-charge lost air: This article describes the steps in draining of a steel compression or expansion tank used on hot water system heating boilers - hydronic heat. Draining water out of a waterlogged expansion tank is a common heating boiler service procedure used to replace a lost air charge.

Energy recovery can be maximized by installing a standard economizer at the outlet of the heat recovery boiler ( the temperature of the combustion gas, which ranges from 120°C to 150ºC, depending on the fuel, can also
Read MoreThe high-pressure liquid enters a boiler, where it is heated at constant pressure to the compressed liquid (Step 2-3) and two-phase (i.e., water and steam) mixture (Step 3-4). The steam is then passed through the superheaters, where it superheated (Step 4-5). The steam is then expanded through a turbine to generate power (Step 5-6).

Read MoreFired reboiler. Fired heaters (Image 3), also known as furnaces, may be used as a distillation column reboiler. A pump is required to circulate the column bottoms through the heat transfer tubes in the furnace's convection and radiant sections. The heat source for the fired heater reboiler may be either fuel gas or fuel oil.
