METHOD FOR RECYCLING MATERIAL WHEN MAKING A MINERAL MELT |
| 摘要 |
The present invention concerns a method of making a mineral melt by burning combustible material in the presence of inorganic particulate material and thereby forming a melt, comprising injecting fuel, particulate mineral material and combustion gas into a circulating combustion chamber (1) through an inlet conduit (4) and combusting the fuel in the circulating combustion chamber (1) thereby melting the mineral material to form a mineral melt and generating exhaust gases; separating the exhaust gases from the mineral melt, collecting the mineral melt (9) and passing the exhaust gases upwards through an exhaust pipe (10) to a conduit (11) of a heat exchange system; and supplying particulate mineral material and a first portion of waste mineral wool into the conduit (11) and pre-heating the supplied material in the heat exchange system, and supplying a second portion of waste mineral wool with a water content between 5 and 25% by weight directly to the inlet conduit (4). |

1. A method of making a mineral melt by burning combustible material in the presence of particulate mineral material and thereby forming a melt, the method comprising the steps of:
injecting a fuel, a particulate mineral material and a combustion gas into a circulating combustion chamber through an inlet conduit, and combusting the fuel in the circulating combustion chamber thereby melting the mineral material to form a mineral melt and generating exhaust gases; separating the exhaust gases from the mineral melt, collecting the mineral melt and passing the exhaust gases upwards through an exhaust pipe to a conduit of a heat exchange system; and supplying a particulate mineral material and a first portion of a waste mineral wool into the conduit and pre-heating the supplied particulate mineral material and first portion of waste mineral wool in the heat exchange system, and supplying a second portion of waste mineral wool with a water content between 5 and 25% by weight directly to the inlet conduit. |
