Camellia Shell Charcoal Powder Molding And Its Combustion Performance

China is a large agricultural country, agricultural residues produced annually was huge, but utilization was low, most could only burn on the spot, not only pollute the environment, and also lead to a waste of energy. Agricultural residues were wood cellulose materials, carbonization of prospects. Continuous pyrolysis pyrolysis equipment based on homemade, to get a Camellia shell of carbon powder as main material, universal testing machine to join a different Binder Camellia shell powder for compression molding, study parameters and Binder addition on carbon powder molding extrusion of particle density density, radial stress, relaxation, specific energy consumption was investigated. By scanning electron microscope analysis of Camellia shell microstructure of carbon powder pellets, thermogravimetric Analyzer before and after contrast Camellia shell charcoal powder molding combustion performance. Main research contents were as follows:(1)The influence of process conditions on the quality of molding fuelUniversal testing machine will be obtained by pyrolysis of oil-tea Camellia shell charcoal powder into cylindrical fuel by changing the pressure, temperature, and moisture content of material, extrusion molding, test of carbon particles from Camellia shell after forming radial pressure, density of extrusion, loose density, specific energy consumption. Results show that increases pressure could improve the quality of forming particles, but the pressure of increasing energy consumption increased, pressure better in the 6 ~8kN. With the increase of temperature, moisture in the material constant evaporation, and adhesive nature of the change, temperature in 80~100℃ better. With the increase in moisture content of materials to reduce energy consumption, but the amount of water added too many poor quality, optimum water co ntent ranges from 15%~20%.(2)Effect of different bonding agent for briquetteThis binder selection of cellulose, lignin, oxidized starch and study on molding pressure was 6k N, temperature 80℃, material moisture content of 20% and different adhesive, and add different particle effects. Oxidized starch as a binder of briquette looks smoother, denser. Use lignin as a bonding agent for briquette of radial stress resistance. Oxidized starch and lignin c ould be used as a carbon shell powder molding binder of Camellia oleifera. Using scanning electron microscopy to various kinds of Camellia shell charcoal powder briquette Binder particles observed electron microscope analysis indicated that separate forming of carbon powder particle surface was very rough, less effective. Added three binders of briquette particles surface was smooth, connections between carbon particles was mainly composed of adhesive bonding, winding, self-locking purpose of forming, forming particles forming effect was good.(3)Study on combustion performance of molding fuelBy the heat gravimetric analyzer and calorimeter for molding raw material combustion test and after forming the granules, results show that tea toner the calorific value was much higher heating value of biomass, and granular briquette combustion occurs mainly in fixed carbon burning phase, 500 degrees Celsius maximum burn speed. Camellia shell carbon powder of fire points about for 380℃, mix bond agent could reduced lit of outside push starting reaction temperature, dang cellulose of added volume in 13% Shi can makes outside push starting reaction temperature reduced to 317℃, oxidation starch of added volume for 9% Shi outside push starting reaction temperature can reduced to 324.7℃, wood quality added volume for 9% Shi outside push starting reaction temperature reduced to 356.9℃.
