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.
EBICO EBS... series burner is the fourth generation of cpmpact type and electronic proportional control digital burner researched and development specially for asphalt mixing plant equipment. This burner is designed according to the three major ideas of European products on safety, environmental protection and saving energy, as well as special environment and fuel requirements of China market. It is a new generation of advanced intelligent electronic proportional control machine which is launched to the market after being approved by lots of test and qualified data. This model is scientific and rational in design, compact in size, complete in structure and low in failure rate. Through the application of many new technologies, it can save 5%~12% fuel and at most about 40% electrical energy; it is an ideal product suitable for both fixed asphalt mixing plant and mobile asphalt mixing plant.
The air supply system is an important component of the combustion system. The evenness, stability and width of the air volume directly affect the combustion effect and adjusting width.
The air supply system is composed of air inlet net cover, motor, bellows, wind blade, soft coupler, air inlet muffler (alternative), full cover muffler (alternative) and avoidance support (alternative).
Steering oil 16 - way composition, available.
Fuel more intelligent control system, adopt international famous brand PLC as the core controller, according to different fuels, the choice of different control procedures, to realize the automatic ignition, automatic flame-out protection system, automatic adjustment, automatic wind load and coal proportion adjustment of oil and gas, combustion fault automatic monitoring alarm, can implement chain and equipment protection, at the same time, the control system can also be used with equipment integration for an organic whole, to realize automatic equipment operation parameters setting and burner operation parameters matching, improve overall equipment automatic control effect.
From the perspective of heat transfer calculation, the measures to reduce the smoke exhaust temperature are analyzed from the following aspects: increasing the heat exchange surface, improving the heat exchange efficiency of the heating surface, improving the heat exchange temperature difference by using a lower temperature source, and reducing the influence of corrosion on the heat exchange efficiency.As gas boiler host first meet the low nitrogen flame furnace volume and size requirements, the second host of convection heating surface is a main export in order to reduce the smoke temperature, general control in 150 ~ 250 ° C, in order to avoid the smoke temperature increases along with the flue design difficulty of heat preservation, high smoking temperature is too low will cause corrosion in furnace convection heating surface forming wall condensation, therefore, furnace domestic demand to design proper heating surface, the physical dimension more representative chamber size.Increasing the heat exchange surface should mainly consider increasing the heat exchange area of the equipment in the rear of the boiler, which is more favorable for rapidly reducing the exhaust temperature.The second is to have a lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, corrosion resistant materials can be used to improve its service life.The new structure of efficient heat exchange mainly adopts the form of staggered tube arrangement, efficient heat exchange finned tube, plate heat exchanger, etc., to increase the flue gas disturbance and contact surface, reduce the heat resistance of flue gas stratification, and improve the heat exchange efficiency of medium and flue gas.
The insufficient capacity of the system to absorb clean energy is mainly reflected in the difference between the regulating capacity of the system and the actual demand for electricity load.In practice, the output of wind power, photovoltaic power and other new energy has a large fluctuation, and there is a big difference between the time period distribution and the electricity load. For example, wind power generally has a large output at night, but the electricity load is small at this time.Photovoltaic power output decreases rapidly in the evening, but the actual power load is approaching the evening peak.Hydropower output is affected by incoming water, flood season output is larger and dry period output is limited.In addition, considering the economy and safety, nuclear power generally undertakes the system basic charge and seldom participates in peak shaving.Under the comprehensive action of all the above factors, the actual dispatching and operation of the system is relatively difficult, and the adjustment ability becomes the key to determine the consumption level of clean energy.
