In today's society has entered the era of knowledge explosion, the fierce market competition make us daily, is full of suffering consciousness, deep well and the future, nip in the bud, the competitive landscape of research and its development trend, only relying on scientific and technological innovation, to provide more professional, more close to the needs of customers products and services, integration of all kinds of resources at the same time, follow the international trend, constantly enrich the latest knowledge, combined with the actual need, enhance the level of professional talents and can make the enterprise develop in the competition.EBICO always takes innovation as the foundation of enterprise survival, insists on scientific research innovation, production innovation, process innovation and product innovation, and constantly improves and extends the product chain to meet customer needs.
At present, the traditional fossil fuels such as coal, oil and natural gas have brought many problems such as environmental pollution and greenhouse effect to human beings.
There are many petrochemical and chlorine-alkali enterprises in China. Many petrochemical and methanol hydrogen production enterprises will produce a large amount of industrial tail gas with hydrogen content of 50%~60% or even more than 90%, which is called hydrogen-rich tail gas.
Hydrogen - rich tail gas is flammable, explosive, large, difficult to transport, and contains certain harmful organic matter, direct emission of environmental pollution;Treatment and utilization of hydrogen-rich tail gas is not only conducive to environmental protection, but also can save energy and reduce costs, thus improving the economic benefits of enterprises.
The air/fuel linkage mechanism includes two servomotors, damper adjusting execution structure and gas flow regulating mechanism.The heat signal is needed to drive the air servo motor and the gas servo motor respectively at the same time.The fuel gas passes through the fuel gas flow adjustment mechanism, and the combustion air passes through the damper adjustment actuator to adjust the input amount of combustion air and fuel gas synchronously in proportion.
In order to ensure that there is an appropriate air/fuel ratio in all working conditions within the load regulation range, a motor is set on the damper and gas flow control valve to adjust the amount of combustion air and gas at each position, so as to achieve full combustion under the condition of low excess air coefficient.When the servo motor rotates, its output shaft directly drives the connecting rod to adjust the valve opening and gas flow valve opening respectively.In the process of debugging, according to the value of combustion supporting air and gas flow in the condition of small fire and big fire, the starting and ending positions of connecting rod linkage stroke are set.
Principle of flue gas recycling:
Some low-temperature flue gas is directly sent into the furnace, or mixed with air (primary or secondary air) into the furnace, because the flue gas absorbs heat and dilutes the oxygen concentration, so that the combustion speed and temperature in the furnace are reduced, because the thermal NOx is reduced.For gas boilers, NOx reduction is most significant.In general, thermal (t-no), rapid (p-no) and fuel (f-no) production pathways are available.The flue gas recycling system is connected with the gas burner. When the inert gas in the circulating flue gas enters the burner, on the one hand, the flame propagation speed will be reduced, and on the other hand, the temperature level in the furnace will be reduced due to the absorption of heat, so the absolute flame temperature will be lowered, which cannot reach the generation temperature. Therefore, the generation of t-no will be inhibited.Other components in circulating flue gas are N2,CO2and H2O in large quantities. As circulating flue gas is mixed in, oxygen concentration in the mixture of air and flue gas decreases, thus affecting the production amount.Mixing circulating flue gas in the air increases the content of N2in the reaction.Due to the high activation energy required for the reaction of oxygen and nitrogen atoms, a large amount of nitrogen failed to react with oxygen to form NO, and reacted with hydrocarbon components in the fuel.A large amount of N2increases the forward reaction of the above equation and generates a large amount of intermediate HCN.The oxygen atoms in the flue gas then react with these intermediate products. The total O2 reaction of HCN in the poor oxygen environment is as follows: HCN+ 5/4O2-+ 1/2N2+CO2+ 1/2H2O;According to the formula, under the condition of lean oxygen and dense combustion, HCN finally generates N2.Therefore, after adopting the flue gas recycling system, on the one hand, the intermediate product HCN increased, while on the other hand, the concentration of O2decreased compared with that before the flue gas recycling was not applicable, which promoted the complete reaction, and the amount of N2was greatly increased, thus reducing the generation of p-no.
After decades of development, EBICO is beginning to enter a critical period of second entrepreneurship.In the face of the changing market, tide business sea, only firm faith, never give up, forge ahead, constantly beyond, can stand the tide.In the future, we will continue to adhere to the safety, energy saving and environmental protection features of EBICO burner, and build EBICO into a value-added brand that leads the market, exceeds the budget and contributes to the society.
New energy enterprises are not only the direct beneficiaries of clean energy consumption, but also important participants, bearing important responsibilities.Participate in the spot power market and auxiliary service market, improve the system dispatching ability in a market-oriented way, and promote the consumption of clean energy.
