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.
A burner is a thermal energy device that converts chemical energy into heat energy and controls and regulates the process of fuel combustion and conversion.The earliest burners in use in the world date back to the middle of the 19th century, when gas was used as an industrial fuel.In the mid-19th century, people reacted air or steam with coal, coke or charcoal at high temperature to make an artificial gas with low calorific value. This artificial gas was mainly made of carbon monoxide and hydrogen, while others, such as carbon dioxide and nitrogen, were very high in content.
Product features
Large adjustment ratio: 1:10, advanced electronic computing proportional mode, steady start up, high temperature control accuracy.
The machine comes with integral compact structure; for the convenience of installation and maintenance, mobile wheel hub device is used
integrally; oil (gas) supply line and control circuit are arranged compactly and ensures systematic connection; it is novel in design and good-
looking.
The fuel oil burner supplies oil at low pressure, air (steam) atomizing and can use poor oil.
Fuel and combustion oxygen are computed and supplied separately, and the ratio is computed respectively by PLC, so as to ensure complete
combustion and increase efficiency by 2%.
The fan applies frequency converting control, so its annual power consumption reduces 30%-40%; featured in high anti-pressure capacity and
strong adaptation, it can control flame easily.
The gas burner applies gas ring atomizing and ensures low NOx emission.
Its safety, energy-saving and environmental protection performance meet European standards.
Its elements are protected by protective measures, level of protection: IP55; that of master device reaches IP56-IP67. It improves safety and
eliminates potential failure.
Applicable fuel: gas, light oil, oil mixture, heavy/residual oil, pulverized coal, oil/gas dual purpose, oil/gas/coal multipurpose, etc.
This series of burner is applicable for model 500-6000 asphalt mixing plant.
Quiet
The newly developed backflow hood type muffler and S-shaped air supply system have greatly decreased the noise level during burner operation. By replacing the traditional external muffler, it is able to offer a quiet environment.
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.
Terminal power users can adhere to the concept of green consumption, priority and the use of clean energy power way, providing clean energy given enough market space, at the same time also can participate in power ancillary services market, with users of interruptible load such as peak shaving service for the system given clean energy resources, enhance the system adjustment ability.
