RESUMO

The industrial plaster production (CaSO4.1/2H2O) in Brazil is carried through by the method of dehydration (calcination) of natural crude gypsum (CaSO4.2H2O), using heat of burning essentially of solid fuels (firewood, oil coke) and liquids (oil BPF, alternative oil). Constant increase in the price of the energy matrix has motivated the calcinadoras to search fuels cheaper. For example, in function of the raised fosseis fuel cost of origin recently the calcinadoras are using firewood of Semi-Ãrido in the hinterland Brazilian Northeastern and contributing for the increase of the desertificaÃÃo of the region. The solid fuel use such as oil coke, results in emission of harmful gases that can cause a great ambient impact due emission of SOx, NOx. However, had to the envolvement of some parameters of calcination, the control is of high complexity, many times generating products of not homogeneous quality. A study of the economic and technological viability for the combustion of gases was carried through (GN+GLP) aiming at to the generation of heat in remote regions for the calcination of crude gypsum for plaster production, calculating the thermal properties of the combustion of the mixture of Natural Gas and GLP in different ratios using a commercial software Acomb5 (IPT) and experimental measurement of PCSs of liquid and solid fuels used in the polar region plasterer. These results will assist in the reduction of the ambient impact minimizing the advance of the desertificaÃÃo due the falling of trees of local trees for burning aiming at to the heat generation, the burning of the gases in direct contact with the product to heat decurrent of a clean combustion, with this, would not have contamination of the product, thus generating a plaster production with controlled quality
