摘要： A method and facility for the hydrothermal carbonization of pasty products or waste, or sewage sludge, in a pressurized reactor heated to carbonization temperature T0. Before entering the reactor, the products undergo: pressurization, and preheating in an exchanger, by a thermal fluid flowing in a closed loop, and receiving heat from products exiting the reactor; the thermal fluid is heated in the loop by an external heat source, downstream from the exchange with the products exiting the reactor, and upstream from the preheating of the products entering the reactor, and the temperature of the product to be treated, preheated by the thermal fluid, when it enters the reactor, is between the carbonization temperature T0 and T0-100° C. The product to be treated flows in at least one tube, where in at least one location therein, liquid is injected to create a liquid ring against the inner wall, and reduce pressure drops.

摘要： The present invention provides a process for the treatment of domestic waste and sewage, where the filtered sewage is heated by the burning of waste, and the sewage under high-temperature and high-pressure pushes a turbine generator to generate electricity. Then the solution-mixture of sewage under high temperature and pressure and the exhaust gas generated by the burning of waste, after neutralization with acid and base, undergoes a drying-treatment by sucking out the water steam, and clean water and residue are finally separated from each other. An apparatus for the treatment of domestic waste and sewage is also produced having a closed incinerator, a turbine generator and a sewage pipe for supplying drive-power/force to the turbine generator. In this way, domestic waste and sewage can be treated together, and meanwhile a weight and volume-reducing, innocuous and energy-generating treatment of the domestic waste and sewage is realized.

摘要： The methods and systems of the present invention reduce NOx emissions in combustion systems, e.g., power plants, boilers, furnaces, incinerators, engines, and any combinations thereof. The inventive process decreases NOx emissions from stationary combustion sources and provides improved utilization of low-grade biomass and other waste fuels without slagging and fouling problems. The invention reduces NOx emissions while utilizing gasified fuels, including biomass and low-grade waste fuels, by gasifying solid fuels and injecting produced gas into a reburning zone of, for example, a boiler at relatively low temperatures and in relatively small amounts. By feeding the gas directly into a reburning zone, the need for gas cleaning is eliminated or substantially reduced as tars are burned in the flame and alkali species may be present at much lower levels than is the case with direct combustion applications.
