Difference between atmospheric residual oil EBICO and supercritical diesel oil EBICO

　　Research and explore a variety of energy joint scheduling.To study the joint optimization operation of thermal power and renewable energy on a pilot basis, and explore the formation of a joint dispatching unit for renewable energy power stations and thermal power plants.The joint dispatching unit is regarded as participating in the power market as a whole and accepting the instructions of the grid dispatching agency.In areas where hydropower is the main source of wind power and photovoltaic power, and in areas where wind power and photovoltaic power are developed simultaneously, pilot joint dispatching units that prevent coordinated operation of multiple power sources by region can be explored.We will encourage new nuclear power projects to build peak-regulating power supplies, such as pumped storage, in combination with local conditions.

　　At present, the traditional fossil fuels such as coal, oil and natural gas have brought many problems such as environmental pollution and greenhouse effect to human beings.

　　There are many petrochemical and chlorine-alkali enterprises in China. Many petrochemical and methanol hydrogen production enterprises will produce a large amount of industrial tail gas with hydrogen content of 50%~60% or even more than 90%, which is called hydrogen-rich tail gas.

　　Hydrogen - rich tail gas is flammable, explosive, large, difficult to transport, and contains certain harmful organic matter, direct emission of environmental pollution;Treatment and utilization of hydrogen-rich tail gas is not only conducive to environmental protection, but also can save energy and reduce costs, thus improving the economic benefits of enterprises.

　　Hydrogen-rich tail gas burner is a kind of industrial gas burner which is developed according to the characteristics of hydrogen burning fast, easy to temper and easy to explode.The product is a proportional adjustable burner with automatic control of forced ventilation, which can realize automatic control operation.With combustion sequence control, proportional control and complete safety protection functions, safe and reliable operation.

　　The most dangerous phase of hydrogen - rich tail gas combustion is the ignition phase.The hydrogen - rich tail gas has high hydrogen content and cannot be used as ignition fuel.Therefore, the igniter of the burner is ignited by LPG, igniting the ignition flame, stable combustion, and then opening the hydrogen-rich tail gas into combustion.Under the condition of open fire and reasonable excess air, there will be no deflagration or explosion in hydrogen-rich tail gas, which ensures the combustion safety of hydrogen-rich tail 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.

　　After straw is processed into liquid fuel, the oil burner can be used to realize automatic control and adjustment.The research and development of straw oil and burner have reached the stage of industrial operation, but the reliability and stability of long-term operation are not up to the requirements of dye properties and burner performance for large and medium-sized thermal energy equipment.
