Steam-Methane Reforming. Most hydrogen produced today in the United States is made via steam-methane reforming, a mature production process in which high-temperature steam (700°C–1,000°C) is used to produce hydrogen from a methane source, such as natural gas. In steam-methane reforming, methane reacts with steam under 3–25 bar pressure (1 ...

Coal is then gravity fed down through the silos toward the pulverizers. There, it is crushed to form a fine coal powder that is pneumatically conveyed to the burners for combustion. Throughout the coal-handling process, the coal can pose significant dust explosion hazards and fire hazards due to self-heating or contact with an ignition source.

This cost is dependent upon fuel type, unit fuel cost, boiler efficiency, feedwater temperature, and steam …

coal are of major importance in the design and operation of steam generating equipment. – The steam coal users, mostly utilities, require optimum calorific value, …

A process of manufacturing coke from coal is described which consists in subjecting it to the action of superheated steam at a temperature of about 1000/sup 0/F. in a closed retort under pressure to remove all smoke-producing elements but retain elements that although volatile at a higher temperature are consumed in combustion. Inventors:

The Koppers-Totzek gasifier has been the most successful entrained-flow gasifier. This process uses pulverized coal (usually less than 74 micrometres) blown into the gasifier by a mixture of steam and oxygen. The gasifier is operated at atmospheric pressure and at high temperatures of about 1,600–1,900 °C (2,900–3,450 °F).
