Research and explore a variety of energy joint scheduling

　　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.abLBoiler Burner

　　In recent years, China's environmental pollution is serious, haze has caused a certain degree of impact on people's life and work.Under the strict requirements of the national environmental protection policy, power enterprises attach great importance to energy saving and emission reduction, and formulate and timely, reasonable and effective measures.For a long time in the future, China will still mainly use coal-fired power generating units to generate electricity, but many boilers of power generating enterprises cannot meet the current national environmental protection requirements.Therefore, coal power generation enterprises must carry out boiler optimization and transformation according to the emission limits of pollutants required by the state, and actively adopt a series of environmental protection measures.Adopting low nitrogen combustion technology in boiler transformation can not only greatly reduce NO emission, but also improve stability and safety of boiler operation and save cost.abLBoiler Burner

　　Principle of flue gas recycling:abLBoiler Burner

　　Some low-temperature flue gas is directly sent into the furnace, or mixed with air (primary or secondary air) into the furnace, because the flue gas absorbs heat and dilutes the oxygen concentration, so that the combustion speed and temperature in the furnace are reduced, because the thermal NOx is reduced.For gas boilers, NOx reduction is most significant.In general, thermal (t-no), rapid (p-no) and fuel (f-no) production pathways are available.The flue gas recycling system is connected with the gas burner. When the inert gas in the circulating flue gas enters the burner, on the one hand, the flame propagation speed will be reduced, and on the other hand, the temperature level in the furnace will be reduced due to the absorption of heat, so the absolute flame temperature will be lowered, which cannot reach the generation temperature. Therefore, the generation of t-no will be inhibited.Other components in circulating flue gas are N2,CO2and H2O in large quantities. As circulating flue gas is mixed in, oxygen concentration in the mixture of air and flue gas decreases, thus affecting the production amount.Mixing circulating flue gas in the air increases the content of N2in the reaction.Due to the high activation energy required for the reaction of oxygen and nitrogen atoms, a large amount of nitrogen failed to react with oxygen to form NO, and reacted with hydrocarbon components in the fuel.A large amount of N2increases the forward reaction of the above equation and generates a large amount of intermediate HCN.The oxygen atoms in the flue gas then react with these intermediate products. The total O2 reaction of HCN in the poor oxygen environment is as follows: HCN+ 5/4O2-+ 1/2N2+CO2+ 1/2H2O;According to the formula, under the condition of lean oxygen and dense combustion, HCN finally generates N2.Therefore, after adopting the flue gas recycling system, on the one hand, the intermediate product HCN increased, while on the other hand, the concentration of O2decreased compared with that before the flue gas recycling was not applicable, which promoted the complete reaction, and the amount of N2was greatly increased, thus reducing the generation of p-no.abLBoiler Burner

　　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.abLBoiler Burner
