It is provided with gas outlet on combustion furnace inner cylinder, is connected to by metal hose with the external plate heat exchanger.
Further, combustor and gravity type venting are provided in the combustion furnace.
Further, thermocouple is additionally provided in the combustion furnace.
Further, the combustion furnace outer cylinder and combustion furnace inner cylinder outer layer are provided with alumina silicate heat-preservation cotton.
Further, the head of the combustor is provided with gas averaging board.
Further, the outside of the combustion furnace is provided with a plate heat exchanger, and the size of heat exchanger is according to actual needs
The exhaust gas temperature of discharge determines.
The beneficial effects of the utility model are embodied in:
1, the efficient direct-combustion furnace of the utility model design uses built-in heat exchanger, is designed by double shell, after burning
High-temp waste gas exchanges heat with the low temperature waste gas for entering cylinder, and wherein combustion high temperature exhaust gas walks inner cylinder, and low temperature waste gas walks outer cylinder
Body, therefore entire combustion furnace realizes burning and heat-exchange integrated function.
2, in addition the design of combustion furnace burning chain-drive section has gas averaging board, can be by flame heat to spread cartridge form jet flames
Amount is radiate in a manner of even circumferential uniformly to be contacted with from external exhaust gas, plays the role of more preferably burning abundant.
3, to guarantee that waste gas burning has sufficient temp and reaction time, inner cylinder redesigns in one layer close to combustor flame section
Heat preservation, prevents low temperature waste gas from contacting by outer barrel with high-temp waste gas, causes high-temp waste gas cooling extent excessive, influences processing effect
Rate problem.
4, to make full use of thermal energy, one plate heat exchanger of combustion furnace exterior design, thus system only needs an external heat-exchanging
Raising efficiency of combustion can be realized in device, reduces fuel and consumes energy and save occupied area function.
