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.

Abstract: The present invention discloses a high-temperature fluid transporting pipeline with a heat exchange apparatus installed therein, a suitable heat exchange apparatus and a heat exchange method, wherein heat contained in a high-temperature fluid can be recovered during the transportation thereof. The heat exchange apparatus comprises a heat exchange body inserted into the high-temperature fluid transporting pipeline, and a heat-receiving fluid coil installed therein. The method of heat exchange is that the high-temperature fluid heats an auxiliary fluid in a heat exchange cavity via a heat exchange panel of the heat exchange body in contact therewith, and the heated auxiliary fluid then conducts the heat to a heat-receiving fluid in the heat-receiving fluid coil.

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: Disclosed are a combustor for fuel combustion and a combustion method therefor. The combustor includes a primary oxidant-fuel delivery assembly, a secondary oxidant delivery assembly, and a tertiary oxidant delivery assembly. The secondary oxidant delivery assembly and the tertiary oxidant delivery assembly are provided on the same side of the primary oxidant-fuel delivery assembly, and the secondary oxidant delivery assembly is located between the tertiary oxidant delivery assembly and the primary oxidant-fuel delivery assembly. The present invention combines the staged combustion and dilution combustion technologies, such that the combustor has a wide flame adjusting range, realizing adjustment of the flame combustion position, flame speed range, flame local atmosphere and flame length, effectively reducing the generation of NOx, and also achieving high heat transfer efficiency.

Abstract: Furnace operation includes consecutive cycles of a heating step, a stopping step and a restarting step. The fuel and/or the oxidizing agent is preheated upstream of the furnace by indirect exchange with the discharged fumes through a medium passing through a chamber. A first wall separates the fumes from the medium in the chamber. The fuel and/or oxidizing agent is separated from the medium in the chamber by a second wall. During restarting, the medium's flow rate Dm is regulated to limit the heating rate of the first wall until it reaches the operational temperature at an end thereof.
