摘要： The invention relates to a method of preparing a mineral melt in a cupola furnace that uses at least one plasma torch to provide heat energy to the furnace. The plasma torch uses nitrogen, carbon monoxide, carbon dioxide, or a mixture thereof as the carrier gas. The invention also relates to a cupola furnace for the preparation of the mineral melt, and the use of a plasma torch in a cupola furnace to reduce the amount of NOx and/or hydrogen in the furnace off-gas.

摘要： The invention relates to a method for manufacturing water treated man-made vitreous fibres (MMVF) comprising:
a. providing a mineral melt,
b. providing a fiberizing apparatus,
c. fiberizing the mineral melt to form man-made vitreous fibres (MMVF),
d. collecting the MMVF, and thereafter
e. applying about 0.1 wt % to about 1 wt % water, based on the weight of the MMVF, to the MMVF to form water treated MMVF.

摘要： A ventilation duct for a fire rated ventilation duct wall penetration has one or more metal sheets forming said duct, wherein said metal sheet duct is covered on the outside by a heat insulating material, and said duct includes elongated stiffening members located on the outside of the duct and attached to said metal sheets. The stiffening members each comprises a metal profile and at least one non-combustible bar of inorganic material. The metal profile is fixed to the metal sheet of the duct and retains the non-combustible bar by at least partly encircling the bar.
