The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1, combined bio matter kitchen range shown in Figure 2 include kitchen range frame 10 and are contained in a plurality of kitchen range cores in the kitchen range frame 10, and present embodiment is two kitchen range cores; Be provided with between adjacent two kitchen range cores and pay a kitchen range core 11, the both sides of paying kitchen range core 11 are respectively equipped with heat pipe 12, and heat pipe 12 is communicated with adjacent kitchen range core; Be filled with refractory material 9 between kitchen range frame 10 inwalls and the kitchen range core and between kitchen range core and pair kitchen range core 11, the refractory material 9 in the present embodiment is water-fast cement; The kitchen range core is provided with the charging aperture 4 that tiltedly reaches outside the kitchen range frame 10, so that the interpolation of fuel is convenient.

Kitchen range core as shown in Figure 3 includes the chamber of a kitchen range 3 and is sleeved on the chamber of a kitchen range 3 outer cooking stoves and overlaps 2, is air supply chamber between the chamber of a kitchen range 3 and the cooking stove cover 2, and an end of the chamber of a kitchen range 3 tube walls and charging aperture 4 is welded to connect; The chamber of a kitchen range 3 its base plates 5 and tube wall are distributed with a plurality of wind pushing holes that are communicated with air supply chamber; The base plate 5 of the chamber of a kitchen range 3 is provided with ash discharging hole, and ash discharge bolt 6 is housed on ash discharging hole; The smoke exhaust pipe 1 that cooking stove cover 2 contiguous chamber of a kitchen range mouth places are provided with 1, two kitchen range core of smoke exhaust pipe is merged into outside smoke evacuation house steward outside kitchen range frame 10.

The chamber of a kitchen range 3 as shown in Figure 4 the nearly upper end position of tube wall place and the described wind pushing hole at nearly lower end position place be circle distribution, this two place is wind pushing hole between the wind pushing hole of circle distribution and is helix and distributes, the helixangleβ of helix is arctg3 π d/H, H is the height of the chamber of a kitchen range, and d is the diameter of the chamber of a kitchen range; The quantity of the wind pushing hole that the quantity of the wind pushing hole that the chamber of a kitchen range 3 distributes in the tube wall of charging aperture 4 one sides and the tube wall of the chamber of a kitchen range 3 opposite sides distribute is than being 8:5; The wind pushing hole that the tube wall of the chamber of a kitchen range 3 and base plate 5 distribute is taper hole, and the small bore end of taper hole is positioned at the described chamber of a kitchen range 3 inwalls; Fig. 5 is the wind pushing hole of the base plate 5 of the chamber of a kitchen range 3; The nearly chamber of a kitchen range 3 lower end position places are the taper hole of circle distribution and the small bore end of the taper hole that is the helix distribution is tilted to, and are shown in Figure 6; The small bore end that is the described taper hole of circle distribution is tilted to down, as shown in Figure 7; Fig. 8 is the expansion schematic diagram of the lead of helix h that distributes of the chamber of a kitchen range 3 tube wall wind pushing holes, calculates the helical pitch of helix and draws expanded view according to the size of the chamber of a kitchen range, press figure and holes in the tube wall line of the chamber of a kitchen range 3.The structure of the chamber of a kitchen range 3 and the distribution of wind pushing hole are the burning feature designs by biomass fuel, and the flame that therefore produces in combustion process is large, the firepower foot, and average intensity of fire is large; Sufficient combustion does not have the slagging scorification phenomenon, and the rear last canescence ashes amount of burning seldom; The thermal efficiency of the core kitchen range of combined bio matter kitchen range is 45% to be higher than the cooking-type stove more than or equal to 35% standard after testing.On the base plate 5 of the chamber of a kitchen range 3 ash discharge bolt 6 is housed, in case be mingled with the impurity such as sand in the biomass fuel, when needing, ash discharge bolt 6 is taken out from the chamber of a kitchen range 3, water is gone out impurity by appendix 7.

During use, the kitchen range core is arranged in work in combined bio matter kitchen range, owing to be provided with pair kitchen range core 11 that is communicated with adjacent kitchen range core by heat pipe 12, can adjacent kitchen range in-core not faced toward the heat recovery that kitchen range mouth top cooker heats, minimizing is airborne heat loss along with flue gas is lost to, and improves the utilization rate of the energy; Because the thermal efficiency of the kitchen range core that present embodiment adopts is 45%, so the waste heat recovery effect is particularly evident, can when cooking operation with the kitchen range core, carry out Baoshang with paying kitchen range core 11.
