Abstract: An apparatus capable of monitoring and adjusting an in-furnace combustion condition in real time, having: a furnace having a heating chamber, a combustor, a charging door, an exhaust gas flow port, and an exhaust gas flow pipe, wherein the combustor is used for introducing fuel and/or an oxygen-containing gas into the heating chamber to form a flame, the charging door is used for adding a raw material, and the gas generated by combustion in the heating chamber enters the exhaust gas flow pipe through the exhaust gas flow port; two sensors of the same type arranged at different positions in the exhaust gas flow pipe; and a control device receiving signals of the two sensors and adjusting, according to a difference between the signals, the amount of the fuel and/or the oxygen-containing gas entering the combustor.

Abstract: Gas distribution component for a burner, comprising an oxidant inlet, for introducing an oxidant flow into the burner; an oxidant inlet channel, in fluid connection with the oxidant inlet; a diffusion/buffering chamber, providing a space for buffering and diffusion of the oxidant after the oxidant flows out of the oxidant inlet channel, and connected to oxidant delivery components, wherein multiple through-holes are provided on a wall of the oxidant inlet channel that is adjacent to the diffusion/buffering chamber, the gas distribution component being easy to operate, with no need to configure a complex valve structure, thereby greatly reducing manufacturing costs, and also achieving the effects of being convenient to use and maintain, reducing the pressure value requirement for an upstream gas source, and reducing the impact of gas source fluctuation on the combustion effect.

Abstract: The present invention discloses a heat exchanger and a heat exchange method, which can recover heat from a high-temperature fluid during transport. The heat exchanger includes a closed heat exchange region and a heat-receiving fluid coil mounted therein. The heat exchange method is to pass the high-temperature fluid through a heat exchange base plate in contact therewith so as to transfer heat to the heat-receiving fluid. According to the design of the heat exchanger in the present invention, modification of the original transport pipeline and mounting of a new apparatus are very convenient, the heat exchange area can be increased while saving the cost, and the heat exchange efficiency is improved.
