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.
In order to achieve environmental protection and low nitrogen emission, gas boiler should consider from three aspects. First, confirm whether the furnace meets the needs of low nitrogen combustion from the heat load parameters of furnace volume and furnace size.Second, confirm the application of low nitrogen combustion technology from the perspective of burner and report the test results in actual use;Three related equipment matching to confirm its rationality from a combustion system, such as single and double fan parameters, flue gas recycling rate, smoke wind mixing way, the precipitation of condensate solution, cold air heating measures, FGR flame stability, FGR impact on the boiler thermal efficiency and so on, analyzed and equipment selection of boiler running safety, stability, the influence of load rate, especially the FGR flame stability of furnace vibration influence;Finally, the conclusion is drawn whether the selected boiler meets the requirement of low nitrogen environmental protection emission.
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.
Quiet
The newly developed backflow hood type muffler and S-shaped air supply system have greatly decreased the noise level during burner operation. By replacing the traditional external muffler, it is able to offer a quiet environment.
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.
In terms of comprehensive energy saving, the equipment belongs to the basic hardware of energy saving, but more importantly, it is the human factor. A good management team can control every link with good people, calculate every energy saving factor carefully in the operation, and constantly summarize and improve the management and control level of the team. This is software.And a company attaches great importance to the energy-saving management operation, not only attaches importance to the construction of hardware, attach more importance to the construction of the software, they generally supporting more advanced computer control system, using the global advanced instruments have been supervised, maximize the gain actual operational data, through the computer system constantly improve, constantly upgrade technology, artificial intelligence will be the face of management thinking into a computer program, using new technology to the automatic control of each node, reduce the human error, omission, precise control of boiler system always run in high efficiency and energy saving state, so,A comprehensive, reasonable and advanced computer control system is the best assistant tool for human management.
Energy saving is a comprehensive project, each node should be controlled, which requires the enterprise to invest a lot of manpower and material resources. The enterprise will constantly improve its management level, and at the same time, it will continue to reap the results of energy saving and consumption reduction, and create better economic benefits.
