摘要： PURPOSE:To enable uniform calcination by a small amount of gaseous fuel, in a shaft type furnace of which the inner diameter becomes larger toward the lower part from the upper part thereof, by providing a preheating drying part, a mixed gas injecting part, a gas combustion part, a calcining part, a cooling part and a cooling air injecting part from the upper part of said furnace. CONSTITUTION:By using a shaft type furnace 1 of which the inner diameter becomes larger toward the lower part from the upper part thereof, a flame and a combustion gas from gas burners 8, 8' are flowed toward a negative pressure part position 6 to carry out the calcination of a material in the region from a position 5 to the position 6. In addition, a cooling air stream due to cooling air jet orifices 11, 11' at a position 7 is flowed toward the position 6 to carry out the cooling of the calcined material between the positions 6, 7. Moreover, the negative pressure part position 6 is formed by sucking the combustion gas and air by suction pipes 14, 14' and the mixed gas of the combustion gas and air is injected from injection pipes 9, 9'. On the other hand, a negative pressure part is formed by sucking a gas by discharge pipes 21, 21' and the drying and the preheating of the material supplied from the supply means 2 provided to the top part of the furnace is carried out while the calcined product is taken out by the taking out means 26 provided to the furnace bottom.

摘要： PURPOSE:To enable to perform smooth firing of pulverized coal for combustion, by installing heating pipe groups for preheating a primary air in the position of a partition wall. CONSTITUTION:A burner 2 is located to the end this side of a rotary kiln 1, heating pipe groups 6, 6'... for preheating a primary air are installed in the upper position of a clinker box 3, being partitioned into a high temperature part 4 and a low temperature part 5, namely the position of a partition wall of a refractory structure which is located in a maner to hang down from an existing ceiling, and a delivery pipe 8 of a high-pressure blower 7 for a primary air is coupled thereto. This permits the supply of the primary air which has high pressure of 1,000-2,000mm. H2O, and high temperature of 300-500 deg.C, and enables the amount of the primary air to be reduced to about 2% of the total air amount.

摘要： PURPOSE:To perform smooth firing and combustion, by coupling the delivery pipe of a blower for primary air to a heating pipe for preheating the air. CONSTITUTION:A primary air, injected together with fuel through a burner 23 installed to the top end of a rotary kiln 11, is pressurized by a blower 27 for primary air, and a delivery pipe 28 thereof is coupled to heating pipe groups 25, 25'... for preheating the air installed in a manner to cover a refractry structure at a corner part 24 at the forward end of the ceiling of a clinker box 1. Thus, the high-pressure primary air flows to the burner 23 as it is heated during passage of it through the heating pipe groups 25, 25'... and pressure thereof is maintained, and the primary air is injected forcibly through the burner 23. In this case, temperature of the primary air fed to the burner is 800-500 deg.C, pressure is 1,000-2,000mm.H2O, and the amount of the primary air can be reduced to 2% of the total air amount.

摘要： PURPOSE: To obtain a stable mixed fuel without forming precipitates of a solid e.g. oil coke, at a low cost, by milling a mixture of water/heavy oil emulsion with the solid fuel into a slurry.
CONSTITUTION: 40W60wt% water is mixed with 60W40wt% heavy oil, preferably heavy oil C having about 200W500cP viscosity, in a mixer 9 to give an emulsion, which is then fed to a mixer 15. Lumpy oil coke, coal coke or coal with a low voltatile content having usually 5W10mmϕ as a solid fuel preferably in an amount equal to that of the emulsion is added thereto, and the resultant mixture is then fully mixed in a mixing part 3, fed to a mill part 4 and milled to such a particle diameter as to pass 95% or more usually through a Tyler 200-mesh screen to give the aimed mixed fuel. When a horizontal mill, e.g. a ball mill, is used as the mill 4, the mixing part 3 is not required.
