TH2791A - A tool for burning fuel and feeding combustion products into melting furnaces - Google Patents

Abstract

The fuel combustion apparatus consists of a chamber (1) for mixing the fuel with a gas-powered oxidizing agent. (2) in which the oxygen filler is introduced into the room (1) like a touch And collector (3) with multiple compartments (4) to carry fuel into the chamber (1) compartment (4) in the collector 3 with the radial forming rod of the collector (3). Pass through the center of each channel (4) at the intersection at at least 10 degrees angle.The channel (4) is constructed so that the fuel flow vector counter to the flow vector of the imported oxygen filler. The chamber (1), through the inlet (2), also includes the combustion chamber (6) which is connected to the mixing chamber (1). At the end of the chamber there is a nozzle (7) which is used for feeding combustion products. Into the melting furnace and there is an 8 way pipe for cooling fluid At least one basin (9) is built between the external surface of the pipe (8) and the inner surface (10) of the nozzle (7).

Claims (4)

Clause (all) that will not appear on the advertisement page: clause 1. Tools for burning fuel The combustion products are fed into the melting furnace consisting of a fuel mixing chamber with a gas oxidant filler. There is an inlet through which the oxygen filler is introduced into the chamber in contact, and there is a large number of collector, a compartment that directs fuel into the mixing chamber. The cavity has its axes, forming the radius of the collector. Drag through the centers of these slots at a point that intersects at least 10 degrees to the axis of the channel. This is directed in such a way that the vector of the imported fuel flow is applied to the mixing chamber and the oxygen filler flow vector that is brought into the mixing chamber. There is a combustion chamber contacting the mixing chamber. Properly established to incinerate the fuel mixture with the oxygen filler. At the end of the chamber there is a nozzle intended to feed the combustion product into the melting furnace. And there are pipes for cooling fluid At least there is one basin to build It is placed between the external surface of the pipe for the cooling fluid and the internal surface surface of the nozzle. It is intended to reduce the amount of heat that is released from the combustion products. 2. Instrument according to claim 1, in which the mixing chamber is provided at least 0.15 deep down along the axis of the mixing chamber. Times of the length of the mixing chamber 3. Tools according to claim 1, which provide a shield placed on the inside of the nozzle. And the shape corresponds to the gap of the nozzle and has a gap that spreads along the perimeter of the nozzle. 4. Tools according to claim 1, in which the nozzles are made of steel or iron, high chromium.
