The steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam. It wasn't until around 1867, with the development of the convection boiler, that the steam-generating industry
Get priceMining Ores recovered by mining include metals, coal and oil shale, gemstones, limestone, and dimension stone, rock salt and potash, gravel, and clay. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed.
Get priceThe mine gas used is a gas that occurs in hard coal mines and consists of methane and carbon dioxide. It is inevitably released during the mining of hard coal, and is therefore extracted as far as possible before the coal is mined. In our gas turbines, gas engines and boiler systems, the mine gas is burned and converted into heat and electricity.
