Title:
鉱物繊維の製造方法及び製造装置
Document Type and Number:
Japanese Patent JP5574708
Kind Code:
B2
Abstract:
The present invention provides a process for making a mineral melt comprising:
providing a circulating combustion chamber which contains circulating chamber gases,
injecting a stream of particulate fuel into the combustion chamber through a fuel feed pipe,
injecting combustion gas into the combustion chamber;
mixing the stream of particulate fuel with the combustion gas and with the circulating chamber gases by injecting into the combustion chamber secondary gas, through a secondary gas inlet, wherein the secondary gas is injected adjacent to the stream of particulate fuel and the injection speed of the secondary gas is at least 100 m/s greater than the injection speed of the particulate fuel;
suspending particulate mineral material in the circulating chamber gases and combusting the fuel, thereby melting the particulate mineral material and forming a mineral melt and hot exhaust gases; and
separating the hot exhaust gases from the melt and collecting the melt.
