The invention provides a lead-free aviation gasoline and a preparation method thereof. The lead-free aviation gasoline is prepared by blending 20-100% of alkanes, 0-86% of arenes, 0-10% of alkenes, 0-20% of nitrogen-containing organic compounds and 0-20% of oxygen-containing organic compounds in percentage by volume together, or prepared by use of a petrochemical refining technology. The alkanes in the lead-free aviation gasoline mainly include isoalkane and cycloalkane, the two of which are low in vapor pressure, appropriate in boiling range, and thus capable of meeting the requirements of the aviation gasoline; the lead-free aviation gasoline is low in all of the content of arenes, the content of alkenes, the content of nitrogen-containing organic compounds and the content of oxygen-containing organic compounds, and thus low in combustion pollution and advantageous for improving the environmental quality of China; besides, the motor octane number of the lead-free aviation gasoline ranges from 90 to 105, and the lead-free aviation gasoline is further high in yield, low in cost and simple in preparation method.

This invention discloses a firing furnace of dust clouds, the middle inner wall of the furnace body is spiral, in the middle of the furnace hearth is the heat accumulator, at the top of the wall of the furnace body is the anti-dust board, on the wall of the furnace body and between the heat accumulator and the anti-dust board are the dust clouds inlet, the diesel oil firing inlet and the primary intake air port, the gasifying furnace chamber is between the hear accumulator and the anti-dust board; the bottom of the furnace is cone-shaped, and the end of the cone is a dust outlet, on the wall of the furnace body and at the bottom of the heat accumulator are the secondary intake air port, the steam inlet, and form the secondary gasifying chamber; the third intake air port is on the wall of the furnace body and the top of the anti-dust board, and form the residual gas burning chamber between the anti-dust board and the top of the furnace body. This furnace can fully fire the plant dust, the efficiency of the burning reaches more than 93%, the temperature more than 1200 deg. C. The heat energy of the burning can use in furnace, the gas turbine, the electricity generating, the heat and cool supply, and etc. It provides the new type technological apparatus for the raw materials utilization.

The invention discloses a biomass granular fuel. The biomass granular fuel is prepared via uniform mixing of following materials and compression moulding of an obtained mixture. The materials comprise, by mass, 50 to 60% of biomass carbon powder, 30 to 40% of municipal organic solid garbage fragment, 1 to 10% of coal dust, 1 to 2% of coal tar, 0.2 to 0.5% of a sulfur fixing agent, and 0.1 to 0.3% of ferrous sulphate. The outer surface of the biomass granular fuel is coated with a layer of biomass polyester. According to the biomass granular fuel, organic combination of biomass energy, mineral fuel, and municipal organic solid garbage is realized; the obtained biomass granular fuel is excellent in caking ability, high in combustion value, and low in combustion pollution, and is beneficial for construction of ecological environment; sulfur dioxide and fly ash are hardly generated; and the outer surface of the biomass granular fuel is coated with a layer of biomass polyester, so that storage and transportation of the biomass granular fuel is convenient, and fragmentation of particles is not easily caused.
