<p>A method and plant for making gypsum products. Crude gypsum lumps are pre-dried and subsequently ground, the ground crude gypsum is calcined, and water is added to the calcined gypsum to produce a material from which the desired end products are formed, which are ultimately dried. A gas turbine is used which drives an electrical generator, and at least a portion of the heat required for calcining is derived from the flue gases of the gas turbine.</p> |
