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.
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.
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.

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.
The insufficient capacity of the system to absorb clean energy is mainly reflected in the difference between the regulating capacity of the system and the actual demand for electricity load.In practice, the output of wind power, photovoltaic power and other new energy has a large fluctuation, and there is a big difference between the time period distribution and the electricity load. For example, wind power generally has a large output at night, but the electricity load is small at this time.Photovoltaic power output decreases rapidly in the evening, but the actual power load is approaching the evening peak.Hydropower output is affected by incoming water, flood season output is larger and dry period output is limited.In addition, considering the economy and safety, nuclear power generally undertakes the system basic charge and seldom participates in peak shaving.Under the comprehensive action of all the above factors, the actual dispatching and operation of the system is relatively difficult, and the adjustment ability becomes the key to determine the consumption level of clean energy.
