Flue gas temperature or flue gas loss | Bosch steam boiler

The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.

Natural Draught and Chimney | Electrical4U

Feb 24, 2012 · We try to calculate the required height of the chimney for a required natural draught for a boiler system. For that, we have to go through two basic equations of gaseous pressure. The equations are Where, "P" is the pressure of air or gas, "ρ" is the density of the air or gas, "g" is the gravitational constant, and "h" is the

Industrial Chimney Manufacturers in India for Boilers

The chimney's working is based on the natural draft or stack effect. As we know, the density of a gas reduces, with rising in its temperature, so because of this reason when the flue gases enter the chimney, the buoyancy forces of air come into action and help in carrying the flue gases out of the chimneys. In the case of a Boiler assembly employing an Induced Draft Fan, the flue gases are

Exhaustive research – accurate flue design for commercial

Biomass boilers and gas-fired condensing boilers are good examples of plants that need accurate flue design to support their efficient functioning. Exhaust gas temperatures from condensing boilers of 55°C and below are achieved through precise control over the combustion, the flow of the hot combustion gases and the transfer of heat into the

Chimney | Engineering | Fandom

A Chimney is a self standing structure for venting hot gases from a boiler to the outside atmosphere [1] and to disperse them at a considerable height. The word 'chimney' also refers to a system for venting hot gases and smoke from a stove, furnace or fireplace to the outside atmosphere. They are typically almost vertical to ensure the hot gases flow smoothly, drawing air into the combustion
