Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment 1
As shown in Figure 1, for a kind of this utility model embodiment 1 structural representation, the detection device 3 that burner 2 that on described CFBB oil, gas integral bed, fuel by the burner wind-box 1 providing combustion air, is burnt by burner, combust monitor forms.Wherein burner 2 includes that burning torch 2-1, oil gun 2-2, ignition air gun 2-3, main air gun 2-4, combination type propulsion plant 2-5 form；Detection device 3 is made up of infrared ray flame detecting device 3-1, ultraviolet flame detection device 3-2, two observation port device 3-3.Burner wind-box 1 is connected on boiler water wall, and burner 2 and burner wind-box 1 pass through Flange joint.Detection device 3 is arranged in burner wind-box end panel.
On CFBB of the present utility model oil, gas integral bed, burner structural dimensions is as follows:
Burner 2 is arranged in the middle part of burner wind-box 1, and wherein arrangement of parts order is followed successively by: oil gun 2-2, burning torch 2-1, ignition air gun 2-3, main air gun 2-4, its horizontal range is respectively L1、L2、L3, oil gun 2-2 and burning torch 2-1 is positioned at left side, and ignition air gun 2-3 and main air gun 2-4 is positioned at right side.Radially burning torch 2-1 and ignition air gun 2-3 is L4 beyond the distance of oil gun 2-2 and main air gun 2-4.
