Fig. 1 is a kind of structural schematic diagram of multi-chamber improved boiler device of the utility model；
In figure, 1- main chambers, 2- fire grates, 3- auxiliary combustion chambers, 5- furnace chambers, the first air supply modules of 8-, the air-supplies of 9- second
Module, 10- third air supply modules, 12- send water vapour device, air-supply arrangement under 13-.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
Embodiment 1, as shown in Figure 1, a kind of multi-chamber improved boiler device, including combustion chamber and fire grate 2, fire grate 2 are set
It sets in the lower part of auxiliary combustion chamber 3 and main chamber 1；It including auxiliary combustion chamber 3 and is led successively according into fuel direction combustion chamber
Combustion chamber 1, the auxiliary combustion chamber 3 are set to 1 side of main chamber.
Auxiliary combustion chamber 3 includes furnace chamber 5, furnace roof and upper air-supply arrangement, space that furnace chamber 5 is constituted along into fuel direction by
Gradual change is big, and furnace roof edge gradually tilts upwards into fuel direction；Upper air-supply arrangement include several air supply modules 8 being arranged on furnace roof,
9,10, air hose is discharged into through setting at least one in each air supply module 8,9,10；The quantity of air supply module can be fired according to auxiliary
