    摘要： A method for desulfurization, denitrification, and oxidation, of carbonaceous fuels including a two stage oxidation technique. The carbonaceous fuel, containing ash, along with an oxygen-containing gas is introduced into a first stage partial oxidation unit containing a molten ash slag maintained at a temperature of about 2200.degree.-2600.degree. F. A flux may also be introduced into the first stage partial oxidation unit for the purpose of increasing the basicity and maintaining the viscosity of the molten ash slag at a value no greater than about 10 poise. The carbonaceous fuel is gasified, and sulfur is chemically bound and captured in the molten ash slag. Since the first stage is operated in a gasification mode (reducing atmosphere), essentially all of the nitrogen in the fuel is converted to diatomic nitrogen, which results in low nitrogen oxide emissions upon final combustion. The first stage is also designed to physically remove a major portion of the fuel ash, the ash leaving the system as a molten slag. The combustible gas derived from partial oxidation (gasification) is directed along a substantially horizontal path to a second stage oxidation unit for final combustion. The sulfur-containing molten slag is removed to a water-sealed quench system or indirect water cooled system for disposal.

    摘要： Large power transformers such as used at electrical generating plants utilize oil for cooling with the heat removed by air cooled radiators. Several air cooled radiators are removed from the transformers and the oil circulated through plate heat exchangers which provide a heat transfer path to a fluid cooling medium such as water. Flow transducers and electrical temperature sensors may be used to monitor the flow rates of the oil and water, and the temperature of the oil and water in various parts of the system. These parameters are controlled to maximize the transfer of waste heat from the transformer to the water. The heated water is then utilized to perform useful work. For example, in a power plant having package boilers, the boiler makeup water is preheated with the transformer waste heat thereby reducing the energy requirements of the system.
