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.
EBICO burner adheres to the three design concepts of "safety, environmental protection and energy saving", and combines the special design of the Chinese market environment and fuel.The product design scientific and reasonable, compact volume, perfect structure, low failure rate, high combustion efficiency, low energy consumption, high waterproof, dustproof, explosion-proof grade at the same time, the eu and China oil, gas road safety device load mandatory safety standards, electronic intelligent matching, operation, adjustment convenient, is the excellent products can fit with thermal equipment.
For large water tube boilers, mixing of FGR recirculated flue gas and fresh air is generally provided with mixing bellows.According to the different layout position is divided into pre - premix and post - premix.Pre-mixing is to arrange the mixing bellows in front of the blower, recirculating the flue gas and fresh air mixed, in the blower into the air, is sent to the burner to participate in combustion, in the mixed air into the air before the air duct set trap, exhaust condensed water, fan selection should also choose anti-corrosion fan.After premix, the mixed bellows are arranged in the blower, and the recirculated flue gas is fed into the mixed bellows through the recirculating blower, mixed with the fresh air from the blower, and sent to the burner for combustion.The commissioning condition of the blower should be good compared with the pre-premixed condition. However, a large amount of condensed water will be generated in the air duct, so the steam trap should be set at the low point of the mixing bellows and the smoke air duct.
Common language symbol, high accuracy intelligent control device, digital intelligent program controller, information feedback and remote transmitting, human-computer interface conversation, quick information reading and understanding barrier-free processing, anticorrosive and heat resistant burning front end, combined air valve, high and low pressure monitoring of EBICO form dual-core safe control.
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.
