Device for reinforcing fuel combustion during ignition initial stages and boosting period

A strengthening fuel burning device in boiler ignition initial stage and in the lifting pressure process belongs to a boiler technology field. The utility model is characterized in that a plurality of air inlet passages and air outlet passages are communicated on an air collecting box, each group of the air inlet and outlet passages is communicated with respective air delivery passage, an one-way baffle plate adjusting device is respectively arranged in the air inlet and outlet passages. The utility model has the beneficial effects that not only the air temperature can be come up to the standard, but also the fuel can be burned better in the boiler ignition initial stage and in the lifting pressure process to decrease the loss of the burning fuel, make the fuel burnt stablly, improve the boiler efficiency, shorten the time of the boiler actuation overall process, and decrease the pollution; thereby the utility model has low investment, simple operation, and high efficiency.
