Title: Equipment applicable to endothermic engines enabling them to operate by means of steam
IPC: F02B/
Filed: 1992-01-27
Granted: 1996-01-15
Abstract: The equipment in question is capable of causing normal endothermic engines to operate with the injection of vaporised water, making use of the high temperature of the exhaust gases in such a way that the superheated vapours are involved in the combustion. In this case, the costs of operating the engine are quite low because the amount of fuel which has to be used is relatively less and is only used for preheating and for bringing the engine up to temperature, and in addition to this there are very few exhaust products, which do not contain harmful gases. Substantially the equipment in question comprises an auxiliary water tank 9, an electronic control unit 5 which determines the delivery of a spray of water through a pump 7 and injectors 8 under the control of sensors 6 placed in the pipes 4 of the manifold. The water is then superheated to 1200 degree C through coils located in openings 10 fitted into the manifold, and is injected into the intake of engine 1 at 1000 degree C. <IMAGE>

Patent TW-260621-B (TW)
IPC: B01D53/34
Filed: 1995-06-12
Granted: 1995-10-21
Abstract: A method of reducing the nitrogen oxide level in the flue gases issuing from combustion units by introduction of reducing agents into contact with gases containing nitrogen oxides in first and second reducing stages, is provided. The first reducing stage is a non-catalytic stage (e.g. at temperatures over 800 DEG  C.), while the second stage is a catalytic stage (e.g. at temperatures of about 300 DEG -400 DEG  C.). A steam generation boiler with improved nitrogen reduction facilities is also provided. The amount of nitrogen oxides in the hot gases is reduced in the combination of the first and second reducing stages while producing steam in a steam generation boiler system, thus resulting in gases essentially free from nitrogen oxides while eliminating the possibility of NH3 (or other reducing agent) slip in the exhausted flue gases. Heat transfers in a convection section as used to establish stabilized temperature conditions for catalytic reduction.
