Multi-fuel CFB boilers typically burn a mixture of waste or alternate fuels along with natural gas, fuel oil,or pulverized coal.This provides an opportunity to produce steam at lower cost than a basic fossil fuel fired unit, but it also makes operations more challenging.Waste and alternate fuels vary in Btu content per volume and their supply is often not consistent. This significantly affects combustion stability and the ability to reliably meet load. More expensive fossil fuels must be used when waste and alternate fuel is not available or to make up for low Btu. Managing this without excessive cost is difficult.In addition, operating within emissions constraints may be a problem with multiple fuel streams in the mix.
With the increase of air supply volume, the mixture of oil mist and air is improved, which is beneficial to combustion. However, if the air volume is too large, the furnace temperature will be decreased and the incomplete combustion loss will be increased. At the same time, the heat loss of exhaust gas will be increased and the power consumption of the fan will be increased because of the increase of flue gas. If the air volume is insufficient, the combustion will be incomplete, resulting in carbon deposition at the tail, which is prone to secondary combustion accidents. Therefore, each blown waste heat boiler header should pass the thermal efficiency test to determine its economic air volume at different loads. In practice, the stoves usually take into account the ignition of the nozzle and the carbon dioxide or oxygen content in the flue gas. Content to adjust the supply air volume. If it is found that the combustion condition of a nozzle is not good, or if the atomization plate with different aperture is replaced, the air pressure of the supply duct should be kept unchanged, and the opening degree of the duct baffle of the nozzle should be adjusted to normal combustion. If the fuel quantity changes due to the change of the oil pressure in front of the furnace, the opening of the fan baffle should be adjusted to achieve normal combustion by changing the air pressure and air volume of the air supply duct when it is necessary to adjust the supply air volume.
3) the observation and analysis of all kinds of flame when adjusting the fuel oil. Generally through the fire point adjustment and flame center adjustment to complete the flame adjustment. The ignition point of the oil mist should be close to the nozzle, but there should be no tempering. Early ignition is beneficial to complete combustion and stability of oil mist. However, the fire is too early, too close to the nozzle, easy to burn the nozzle and furnace wall to determine the mouth. Furnace temperature flying oil varieties and atomization quality, as well as air volume, wind speed and oil temperature, will affect the distance and proximity of the ignition point. So if you want to adjust the ignition point, you should find out the cause in advance, and then take targeted measures. When the boiler load is constant and the oil pressure and oil temperature are stable, Should be based on the ignition point wind speed and wind distribution situation.

Steam is generated in the heat recovery steam generator (HRSG). The HRSG recovers the waste heat available in the combustion turbine exhaust gas. The recovered heat is used to generate steam at high pressure and high temperature, and the steam is then used to generate power in the steam turbine/generator.Get a Quote

2019-8-19·A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubesGet a Quote
Combustion. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Nuclear fission is also used as a heat source for generating steam. Heat recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbines.Get a Quote
