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.
The "medium pressure air-tumber" atomized burner developed for burning straw oil has good applicability not only to straw oil, but also to bio-oil and petroleum oil.This kind of burners can be used to realize the normal combustion of heavy asphaltene and colloid and inferior oil with high density.
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.
Terminal power users can adhere to the concept of green consumption, priority and the use of clean energy power way, providing clean energy given enough market space, at the same time also can participate in power ancillary services market, with users of interruptible load such as peak shaving service for the system given clean energy resources, enhance the system adjustment ability.
