EBICO is based in Italy and the burner business is one of our strengths.We have formed strategic cooperation with Novar Bergamo and Vizcaya teams with strong burner development capabilities internationally.Optimize and integrate the cutting-edge combustion technology resources in Europe to form EBICO's cutting-edge strategic system.With strategic partners or factories in Italy, Germany, Switzerland, the Netherlands and China, we have decades of experience in the design, development, marketing services and resource optimization of large burners, fuel supply systems and automatic control systems.Our research focuses on large industrial burners, non-standard burners and some highly refined combustion equipment.
EBICO provides standard and non-standard burners.The scientific application of advanced separation technology determines that it can adapt to very harsh environment, EBCIO burner fully meets the requirements of boiler, power plant, industrial boiler, heat conduction oil furnace, asphalt mixing building drying cylinder and asphalt heat conduction oil furnace.Advanced and unique design concept has won the EBICO burner many markets, such as: low nitrogen emission standard burner and intelligent control which meet European CLASS I, CALSS II and CALSS III standards in advance.EBICO burner provides customers with the most reliable products and services, while achieving a variety of fuel efficient and economical configuration.At present, there are many burners for boilers, power plants, industrial boilers, thermal oil boilers, garbage incineration, asphalt mixing building heating services.
EBICO burner has a team of highly technical professionals who are able to analyze customer requirements and discuss the best design and manufacturing systems with the customer to fully meet the specific requirements and expectations of the user.The most important thing is to provide fast support service for customers.
The choice of EBICO burner means that we have experienced partners with the same needs in the same industry, which enables the users to allocate economic and production resources to the maximum extent under the premise of fully considering the ecological and environmental issues.
We can provide all kinds of burners with power range of 85kw-86000kw.Specific are: conventional fuel burner, non-standard custom burner, low nitrogen burner, pulverized coal burner, multi-fuel burner, low calorific value burner.
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.
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.
Clean energy consumption and utilization is a systematic problem involving power supply, power grid and power load.At present, the consumption of clean energy in China is mainly faced with the following difficulties: first, the reverse distribution of resources and demand. Most of the landscape resources are distributed in the "three north" region, while the water energy resources are mainly concentrated in the southwest region, while the power load is mainly concentrated in the central, eastern and southern regions.Second, the rapid development of clean energy does not match the growth rate of electricity consumption in recent years. In recent years, with the active support of national policies, the installed capacity of clean energy, especially wind power and photovoltaic power generation, has maintained a fast growth rate, far exceeding the growth rate of electricity consumption of the whole society.Third, the processing of wind power and photovoltaic power generation is affected by natural conditions, and there are relatively large fluctuations. After large-scale grid connection, it brings great challenges to power system dispatching and operation.At present, China's power system is not fully adapted to such a large scale of volatile new energy access.
