Abstract
The invention discloses an efficient biomass steam boiler which comprises a shell and a boiler body arranged in the shell. The shell is rectangular, and the boiler body is of a double-boiler-cavity structure and composed of a heating cavity and a steam cavity. The heating cavity comprises a combustion chamber and an air chamber, wherein the combustion chamber and the air chamber are arranged up and down and are separated by a resistance fire grate in the middle. An inner container is arranged in the steam cavity, and a chimney communicated with the inner container is arranged on the top of the steam cavity. A water inlet pipe and a water outlet pipe are arranged on the inner container. An air draft device connected with the chimney is arranged on the shell. A feeding device is arranged on one side of the heating cavity. A control box is arranged on the shell, and a low-pressure protection valve connected with the air chamber is further arranged on the shell. The combustion efficiency is improved, and safety is improved.
Description
Technical field
The present invention relates to biomass boiler field, particularly a kind of efficient biomass steam oven.
Background technology
In recent years biomass fuel exploitation, recycle, produce and receive unprecedented concern.The agriculture and forestry organic waste material that the raw material of biomass fuel is mainly got; inexhaustible; by a series of deep processing; usually biological particles or powder is produced; changing into biomass energy after both being burnt respectively is that industry provides alternative energy source; not only solve the process problem of agriculture and forestry organic waste material, also reduce CO2 and pernicious gas to airborne release.
In the equipment of existing biomass burning, the air admission hole of combustion chamber is arranged on the bottom surface of combustion chamber, and like this in the process of fuel combustion, air is from the bottom up-draught of fuel the bottom surface of combustion chamber, and fuel is lighted and realized burning under the effect of fire rod.Air admission hole in above-mentioned combustion chamber achieves mixing of fuel and air, but along with the carrying out of burning, the ashes that fuel combustion produces and unburnt material can block the enterprising pore in bottom surface, combustion chamber and then impact burning in certain degree, so material burns, the ashes produced need to be drained in time in the process of burning, but ash disposal just can must be carried out after fuel combustion, therefore once air admission hole blocking stove will quit work, cleaning wastes time; And fuel take fire ashes do not get rid of during in, because above-mentioned air admission hole is just distributed in the bottom of combustion chamber, and certain unburnt gas is there is on top, combustion chamber, under the impact of the air-flow that these unburnt gas lead in bottom, drain from combustion chamber when non-Thorough combustion, so not only cause fuel combustion insufficient, utilization rate is low, waste living beings value originally, also make those high-temperature flue gas with unburnt gas and ashes discharge contaminated environment simultaneously.In addition, because this biomass heat-conduction oil oven does not arrange blower fan, cause it that air-flow cannot be made in the running to drive flame High Rotation Speed in combustion chamber, operating efficiency is lower.
