With the continuous promotion of coordinated development of city clusters in key national regions, urbanization strategy and rural revitalization strategy, the degree of urbanization development in China has been gradually improved. In recent years, the scale of cities has been rapidly expanded, people's consumption level has been constantly improved, and garbage production has been increasing, and many cities have been surrounded by garbage.In the section of "accelerating the reform of ecological civilization system and building a beautiful China", the 19th National Congress of the Communist Party of China (CPC) listed the issue of garbage treatment as "prominent environmental problems", and clearly required "strengthening solid waste and garbage disposal", so as to form a space pattern, industrial structure, mode of production and way of life that can save resources and protect the environment.How to deal with waste reasonably and effectively has become the focus of environmental protection for the government and the public.At present, under the principle of waste disposal reduction, recycling and harmless, waste incineration power generation gradually shows great advantages and forms a competitive emerging industry, which has become an important development direction of waste disposal.
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.
Different gas pressure regulating valve sets provided by EBICO can be designed and matched separately according to different projects. The general supply includes manual globe valve, filter, pressure regulating valve, expansion joint and pressure gauge. The gas pressure regulating valve sets have the characteristics of keeping pressure stable and cleaning gas.
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.
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...
