Learn MoreThe 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%.

A flue-gas stack is a type of chimney, a vertical pipe, channel or similar structure through which The flue gas stacks are often quite tall, up to 400 metres (1300 feet) or more, so as to disperse The chimney is part of a steam-generating boiler, and its

Learn More. 18 °C for boilers operating in WINTER only. 30 °C for boilers operating throughout the year Exemple : if h c = 94 % for gas with 15 % excess air, is obtained for a boiler running throughout the year: Temp flues = (132 - 30) Temp flues = 102 °C at the entrance to the chimney.

Learn MoreFeb 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

Learn MoreThe 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

Learn MoreBiomass 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

Learn MoreBoilers or furnaces equipped with induced draught fans should have a chimney efflux velocity of not less than 8 m/sec at full load for boilers rated up to 13,600 kg/hour increasing to a maximum of 15 m/sec at full load for boilers rated at 204,000 kg/hour. 10 The method of calculation of final chimney

Learn MoreTo determine the height and diameter of the chimney for the boiler room, it is necessary to perform an aerodynamic design calculation. The diameter depends on …

Learn MoreThe material of the entire steam boiler flue gas system must be suitable for temperatures up to 350°C. If the boiler is equipped with a fourth pass or a waste heat boiler for utilisation of the waste heat in flue gases from a CHP module or a gas turbine, the flue gas system must be suitable for the highest temperature that can occur in each case.

Learn MoreThe height and diameter of the chimney is designed by the planning engineer. It depends on the type of building, where the chimneys reach different heights from 7 m to 15 m. A chimney with insufficient height could cause insufficient draft, because there is not enough time to to remove the amount of flue gas produced from the boiler in the

Learn MoreMar 05, 2019 · The pressure difference in the chimney pulls air and fuel gas from the boiler or fireplace ….

Learn MoreThe cross section of the chimney channel in area should be no less than the cross section of the nozzle of the gas boiler, with which the device is connected to the chimney. When constructing and connecting chimneys for gas boilers over their entire length, narrowing of the channel, curvature and the use of modules that are not suitable for the

Learn MoreJun 11, 2012 · Velocity is known and hence the area can be calculated. For Baggasse fired Boiler, the Theoritical air required is 5.76 Kgs/Kg. of Baggasse with 50% Misture. The Modern Sugar Factory has 35% Excess Air. Hence it is easy to calculate the Chimney Area. Regarding the HEIGHT of the CHIMNEY, it is governed by 2 Factors.

Learn MoreA 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
