Waste incineration power generation is an important new energy industry related to people's livelihood.China has basically clarified the development direction of industrialization and marketization of waste treatment from the perspective of industrial policy.Since 2016, the state has formulated a series of policies and measures to promote the sustainable and healthy development of waste incineration power generation. The National Energy Administration, the former ministry of environmental protection, and the ministry of housing and urban construction have also issued relevant documents to support the development of waste incineration power generation industry.
However, as a pre-work of garbage incineration power generation, the methods related to garbage classification and recycling have not been clarified and implemented, and there are not enough constraints and incentive mechanisms to make garbage classification universal, which cannot create good conditions for harmless garbage treatment and garbage incineration power generation.At the same time, the corresponding design, manufacturing specifications, standard boxes of various investment, tax, subsidies and other policies still need to be further improved, especially the garbage treatment subsidies policy, in the vicious competition appeared unstable phenomenon.It is the key to formulate corresponding preferential policies for waste incineration power generation in developed countries. Without preferential policies and various subsidies, it is difficult for waste incineration power generation to be industrialized.Therefore, the relevant laws and policies of waste incineration power generation industry and related policies, norms and economic policies are to be improved.
In order to achieve environmental protection and low nitrogen emission, gas boiler should consider from three aspects. First, confirm whether the furnace meets the needs of low nitrogen combustion from the heat load parameters of furnace volume and furnace size.Second, confirm the application of low nitrogen combustion technology from the perspective of burner and report the test results in actual use;Three related equipment matching to confirm its rationality from a combustion system, such as single and double fan parameters, flue gas recycling rate, smoke wind mixing way, the precipitation of condensate solution, cold air heating measures, FGR flame stability, FGR impact on the boiler thermal efficiency and so on, analyzed and equipment selection of boiler running safety, stability, the influence of load rate, especially the FGR flame stability of furnace vibration influence;Finally, the conclusion is drawn whether the selected boiler meets the requirement of low nitrogen environmental protection emission.
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.
Integrated control system is that we proposed earlier today's more advanced control mode, is widely used in Europe and the us some dimensions industry in our country and demanding enterprises choose this control concept, its core idea is to put the boiler and burner control together unified programming, making accurate digital control, this control model to avoid the original control of shortcomings, such as: scattered, incompatible, multipoint multiple handling, economic problems.
Its advantages are obvious:
Software compatibility optimization, electronic control uniformity, greatly improve the control accuracy, energy saving
Design and manufacture consistency, safety and reliability and production cost savings
Single human-computer interface dialogue
Operating system intuition
Improve maneuverability and safety
Single professional debugging, to ensure safety and efficiency
Continuity of one-stop after-sales service, greatly improve the work efficiency, reduce the service cost for users
One-click accessories, software and supply upgrades are guaranteed
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.
After straw is processed into liquid fuel, the oil burner can be used to realize automatic control and adjustment.The research and development of straw oil and burner have reached the stage of industrial operation, but the reliability and stability of long-term operation are not up to the requirements of dye properties and burner performance for large and medium-sized thermal energy equipment.
