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.
Many projects to increase the flue gas external circulation, according to the on-site reaction, the flue gas recirculated condensed water is a lot, in winter, the wind duct will even freeze.This is because the hot and humid smoke and combustion fresh air mixed, mixed steam beyond the mixed air temperature of the saturated humidity, the excess steam formed condensed water.CO2 in the flue gas will dissolve in the condensed water. If the acidic condensed water enters the burner or fan, it will easily corrode the components of the burner or fan.Measures must be taken to prevent condensation from entering the burner or fan.Add heat preservation for recirculating smoke pipe, reserve condensate water outlet, fresh air and preheat.
Condensate water discharge device shall be set at the lowest point of each section of the circulation flue. If there is a mixing bellows, condensate water discharge device shall be set on the mixing bellows. If necessary, condensate water discharge device may also be set on the fan.Condensate water discharge device recommended made of water seal type, the highest point of the water seal lower than the lowest point of the flue gas pipeline, for the convenience of condensate water discharge.
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.
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.
EBICO burner products through the investigation, design, testing, finished products, certification, feedback, innovation, guidance eight steps, the safety, energy saving, environmental protection of EBICO series products deductive incisively and vividly, this kind of demanding requirements we are still continuing...
