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.
In addition to the installation of the fan in accordance with the relevant standards and in accordance with the design drawing requirements for construction.The fan shall be installed in a position to ensure normal operation and easy maintenance of the required controls.
During installation, it is recommended that the fan and the air duct adopt soft connection (flexible material and non-combustion), the length should not be less than 200mm, and the pipe diameter should be the same as the inlet and outlet size of the fan.In order to ensure that the soft connection does not appear distortion in the process of system debugging, the installation should be moderately tight.The pipe diameter of the smoke and air duct at the outlet of the fan can only be enlarged, not reduced.Pay attention to the direction of airflow if there is a guide plate in soft connection.
A soft connection is also suggested between the inlet of the burner and the air duct, and the air duct between the blower and the burner should maintain a certain Angle.Vertical arrangement is not easy to cause uneven combustion and vibration.Fan into the tuyere are generally adjustable door, the installation of inlet damper should pay attention to whether the direction of guide flow formed by the blade Angle when opened is consistent with the impeller rotation direction.
Maintenance
The frame is fully movable; both the frame and the control system have full-open doors, so the machine can be maintained easily after moving the main frame forward and backward or opening those doors. Such quick and efficient maintenance service owes to the design experience of EBICO integration module system.
Enough about how to solve the trouble of burner
In terms of comprehensive energy saving, the equipment belongs to the basic hardware of energy saving, but more importantly, it is the human factor. A good management team can control every link with good people, calculate every energy saving factor carefully in the operation, and constantly summarize and improve the management and control level of the team. This is software.And a company attaches great importance to the energy-saving management operation, not only attaches importance to the construction of hardware, attach more importance to the construction of the software, they generally supporting more advanced computer control system, using the global advanced instruments have been supervised, maximize the gain actual operational data, through the computer system constantly improve, constantly upgrade technology, artificial intelligence will be the face of management thinking into a computer program, using new technology to the automatic control of each node, reduce the human error, omission, precise control of boiler system always run in high efficiency and energy saving state, so,A comprehensive, reasonable and advanced computer control system is the best assistant tool for human management.
Energy saving is a comprehensive project, each node should be controlled, which requires the enterprise to invest a lot of manpower and material resources. The enterprise will constantly improve its management level, and at the same time, it will continue to reap the results of energy saving and consumption reduction, and create better economic benefits.
