21MW YQL gas-fired thermal oil heater for chemical industryThermal oil heater is used to provide heat energy for the reaction and fractionation process of residual oil hydrogenation in chemical industry. Shandong Guangyue Chemical Co., Ltd. is a new comprehensive chemical enterprise, which is engaged in petroleum processing, warehousing logistics and international trade services. The construction of its second project starts in 2018, planning to build 1.6 million tons residual oil hydrogenation each year. ZOZEN has rich experience in chemical industry. ZOZEN’s manufacturing technology of thermal oil heater is unique and inimitable, ensuring the high quality of 50gallon pot still distillation boiler pot stills. After professional explanation by ZOZEN’s engineer, this project leader ordered one set of 21 MW YQL series gas-fired thermal oil heater. This thermal oil heater adopts multi-return coil tube design, which features safer operation, sufficient heating surface and 95% thermal efficiency. It is also equipped with low nitrogen burner for energy saving and environmental protection.

Other materials may be appropriate to improve the gas burner in the 50gallon pot still distillation boiler pot still, it is recommended to select excellent alloy materials, wear resistant and add functions. Swirl vanes use high temperature stainless steel materials, so that the rotary blade can be avoided because of falling combustor burning nozzle configuration of deformation damage.

How Henan gas 50gallon pot still distillation boiler pot still flue gas to reduce combustion temperature by using Henan gas boiler flue gas recirculation control NOx by external and internal flue gas recirculation techniques. Reduction of the combustion temperature Henan gas boiler flue gas can be achieved by adding the flame region, thereby absorbing the added flue gas lowers the combustion temperature. Henan gas boiler combustion products through the flue gas is added to the combustion zone, not only lowers the combustion temperature, NOx formation is reduced; simultaneously added to the flue gas reduces the oxygen partial pressure, oxygen and nitrogen that will reduce the thermal NOx generated process, thereby reducing the formation of NOx. Depending on the application of the principle, flue gas recirculation applied in two ways, Henan gas boiler are recirculated flue gas recirculation and internal external flue gas. For external flue gas recirculation techniques boiler, the flue gas from the outlet of the boiler via an external conduit, re-added to the furnace. According to the study, external flue gas recirculation Henan gas boiler can be reduced to 70% of NOx formation. The ratio of the outer loop NOx control effect has a greater impact, as the outer loop increases the proportion of NOx reduction rates are more obvious, but the electrical energy consumption for circulating air will also increase. For internal boiler flue gas recirculation, gas back into the combustion zone through the main dynamics of the gas burner. Primarily through internal flue gas recirculation speed jet flame entrainment or swirl burner so that the air flow generated rotational achieve a circulating effect. It is generated by using a cyclone or a tangential inlet into a gas stream with a stream tangential velocity, i.e., rotation of a vortex. The strength of the vortex may be a dimensionless swirl number S of FIG. When the degree of swirl exceeds 0.6, the gas stream will have sufficient radial and axial pressure gradients, which can cause reverse airflow, to produce a circular center of the flame recirculation zone.

Cooperation with the fast 50gallon pot still distillation boiler pot still really is a very correct decision of our hospital. The party quickly boiler shell not only provides us with high-quality and high-performance energy saving boiler coexist; also provides free installation and post operation and maintenance personnel training services for our system, very caring, thoughtful. --customer feedback
