摘要： PURPOSE:To cause combustion to be stable and enable combustion heat to be efficiently recovered from combustion gas by a method wherein a liquid fuel supplying angle is specified at a lower level than that of a feeding port of secondary lower stage air into a fluidized bed combustion chamber. CONSTITUTION:Liquid fuel is supplied into a liquid fuel supplying pipe 35 mounted at a lower level of a secondary lower stage air feeding pipe 24 from a fuel injection gun 36 at the same central axis. At this time, a level ratio between the supplying pipe 35 and the secondary lower stage air feeding pipe 24 is from 0.3 to 0.8. Liquid fuel is supplied from the liquid fuel injection gun 36 having an angle formed between an axis of the liquid fuel injection gun 36 and a horizontal line within a vertical line including the axis of 5 to 20 deg. and then the liquid fuel is ignited. As a result, a maximum temperature within the combustion chamber is 850 deg.C, a concentration of monoxide carbon is 180ppm and a concentration of SO2 is 90ppm, resulting in that a superior combustion state can be attained.

摘要： PURPOSE:To enable burning gaseous fuel in a manner of multifuel combustion in safety, without raising environmental problems, and highly efficiently in a circulating, fluidized bed type combustion chamber with a two-stage supply of air by a method wherein gaseous fuel is fed through a pipe provided inside a secondary air-feeding pipe and a specific relationship is maintained between the amount of secondary air fed through a lower-level inlet and the flow-rate of gaseous fuel. CONSTITUTION:Granular coal 1 and limestone 3 are fed into a fluidized bed combustion chamber 6 by a feed pipe 5 and primary air blown into the fluidized bed combustion chamber 6 by a primary air-feeding pipe 8, which is connected to the bottom of the fluidized bed combustion chamber 6, keeps the granular coal 1, limestone 3, etc., in a fluidized state. A secondary air upper-level feed pipe 9 and a secondary air lower-level feed pipe 24 are connected to the fluidized bed combustion chamber 6 and a gaseous fuel feed pipe 25 is connected to the fluidized bed combustion chamber 6 in a concentric arrangement inside the secondary air lower-level feed pipe 24. Under this piping arrangement the feeding of air and gaseous fuel is made to maintain a relationship between Q1 representing the amount of secondary air at the lower level, i.e., the stream through the secondary air lowerlevel feed pipe 24, and Q2 representing the flow-rate of the gaseous fuel, i.e., the stream through the gaseous fuel feed pipe 25, expressed as Q1/Q2>=0.3A0 where A0 represents a threoretical amount of air for combustion against gaseous fuel.

摘要： An immersion cooling apparatus includes a mechanism for immersing a hot metal pipe with the axis thereof directed horizontally in a cooling tank containing cooling liquid, and a mechanism for locking the immersed pipe in position in the cooling tank. While the locking mechanism is preventing the pipe from moving, a nozzle extending toward the interior of the pipe in the direction of the pipe axis injects cooling liquid into the pipe. The cooling liquid thus injected flows completely through the pipe so that the pipe being cooled is not injured or bent.

摘要： Sinking of a charge in a cross-sectional direction of a melting furnace is made uniform, poor heat-exchange between the charge and a gas due to improper sinking of the charge and local concentration of a gas flow is reduced to minimum, a melting condition of wastes is stabilized irrespective of the composition of the wastes, and a charge of a treating speed of the wastes is restricted, too. A plurality of lower stage tuyeres are disposed vertically in a burning/melting zone, carbonaceous mass-like inflammable matters are mainly burnt by supplying a combustion support gas, a plurality of upper stage tuyeres are disposed vertically in a plurality of stages at the positions above the tuyeres, and a part of the wastes is burnt by supplying the combustion support gas. In this instance, the combustion support gas equivalent to oxygen content of 130 to 600 Nm3/t of wastes is supplied, and the combustion support gas is supplied from the upper stage tuyeres so that the proportion of the oxygen content from the upper tuyeres is 0.2 to 0.8 of the sum of those of the lower and upper stages. Further, the supply quantity is controlled so that the oxygen content supplied from the lower stage tuyeres is at least 0.8 times the theoretical oxygen content of the carbonaceous mass-like inflammable matters, and the exhaust gas temperature on the packing layer of the wastes is set to 150 to 700 °C.

摘要： PURPOSE:To omit a working space around a culture vessel and increase a cultivation area by floating setting plates onto the water surface of the culture vessel, providing water jetting ports at one end of the culture vessel and transferring the setting plates with the thrust of jet streams discharged from the water jet ports. CONSTITUTION:Setting plates 3 are floated on the water surface of a culture vessel 1 and water jetting ports (7a) and (7b) are arranged at one end of the culture vessel 1. The setting plates 3 are transferred with the thrust of jet streams (8a) and (8b) discharged from the water jetting ports. As a result, operation of harvesting, planting of seedlings, etc., can be carried out by one worker 9 without changing a working position at one end of the culture vessel. Thereby, a working space need not be ensured around both sides in the longitudinal direction of the culture vessel and around the end face on the opposite side and each culture vessel can be installed in close contact without any problem of work in installing the plural water culture vessels in a greenhouse. Consequently, the cultivation area can be increased to increase yield.
