Analysis On The Existing Problems Of Energy Saving And Emission Reduction Of Industrial Boilers And Their Solutions

My country's energy industry, steel industry. As well as the collective heating in the north in winter, boilers are used. The structure of industrial boilers has helped the development of our industry. Once upon a time, the high chimneys of boilers were the proof of development. However, with people's awareness of environmental protection and the continuous development of energy and industrial industries, industrial boilers have high resources. Waste and pollutant discharge are gradually criticized by people, but the development of industry and people's daily life are still inseparable from the use of industrial boilers. Therefore, it is very important for the energy-saving renovation of boilers to improve the energy utilization rate of boilers and reduce The emission of pollutants has changed the original phenomenon of boilers wasting a lot of energy. At the same time, to learn to use the heat energy in the chimney and do a good job in the secondary utilization of energy, it is necessary to have a clearer understanding of the problems of existing boilers, and then put forward corresponding industrial boiler rectification measures. To achieve the corresponding purpose of protecting the environment and saving energy.

1. Problems existing in industrial boilers

1.1 Design defects of the industrial boiler itself

In order to improve the energy utilization rate of industrial boilers and reduce pollutant emissions, it is necessary to understand the structure and properties of industrial boilers, so as to realize energy saving and emission reduction of industrial boilers. First of all, industrial boilers have major defects, which are determined by their innate nature. No matter how well energy-saving and emission-reduction work is done, there is still a certain limit to the energy conversion rate. There are many characteristics of industrial boilers. First of all, the capacity of industrial boilers is small, because they are made of iron, so they are limited by volume. In addition, in the long-term use of industrial boilers, there will be a lot of coking on the heating surface, accumulation of dust, etc., which seriously affects the heat transfer rate of the boiler and reduces the heat conversion capacity. All are wasted in the air, resulting in a great waste of energy. At the same time, industrial boilers also have the problem of excessive water pollutants. Many industrial boilers in my country do not have corresponding self-control systems, and the level of intelligence is low. In addition, the quality of many boilers cannot be guaranteed, which not only pollutes the environment, but also wastes a lot of resources by using boilers for residential heating institutions, or using boilers The quality of the products obtained by the producing enterprises is often substandard.

1.2. Problems existing in energy saving and emission reduction of industrial boilers

The energy saving and emission reduction of industrial boilers needs to be carried out from multiple aspects at the same time. In the development of the industry, the working efficiency of industrial boilers is controlled by five factors, which are personnel, fuel, the boiler itself, automation equipment, and control technology. People are the principle personnel of the boiler, and their corresponding quality level affects the efficiency of the boiler, and it is also related to whether the boiler can be found at the first time when there is a problem, which is of great importance to the use of the boiler. Fuel is the energy for combustion, and the energy must be matched with the boiler. If the energy is too large, it will cause unnecessary waste. In addition, insufficient energy will affect the quality of the product and cause greater pollution. The control technology needs to realize the real-time monitoring of the boiler, and timely find out and notify the relevant personnel when there is a problem. Automation technology is the problem of controlling the process in the operation of the boiler,

First, the relevant personnel in the industrial industry and those involved in the implementation of energy-saving and emission-reduction work failed to fully recognize the five elements that affect energy-saving and emission-reduction work, so they failed to take the five elements of people, materials, furnaces, machines, and control as a system. Comprehensive and coordinated development of the project, comprehensive and long-term overall planning of problems and finding solutions to problems.

Secondly, the energy policies issued by the relevant state departments and the relevant public opinion environment failed to form a real pressure on the energy saving and emission reduction of the industrial boiler industry. On the one hand, the relevant departments failed to take corresponding measures to publicize the importance of non-renewable energy such as coal, and on the other hand, did not take strict control over the development and utilization of non-renewable resources, so that the industry personnel did not form the urgency of this work. important knowledge. At the same time, the current public does not have a clear understanding of the pollution caused by industrial boilers, and there is no public opinion pressure on energy conservation and emission reduction in the industry.

Thirdly, the use and management level of industrial boilers is low, and the overall quality of operators needs to be improved. At present, the technical quality of industrial boiler operators in my country is generally low. Most industrial boiler operators lack comprehensive and systematic technical training and learning of boilers, fail to fully and effectively master the operation skills of industrial boilers, and lack corresponding The maintenance methods of industrial boilers will affect the effective use of industrial boilers, and also bring certain difficulties to the energy saving and emission reduction of industrial boilers.

Finally, industrial boilers operate at a very low level of automation. The industrial boilers currently used are generally not equipped with operation monitoring instruments, which leads to the fact that when the relevant operators adjust the boiler combustion conditions, they cannot adjust the boiler operation conditions in time according to the load changes, resulting in waste.

2. Measures to promote energy saving and emission reduction of industrial boilers

2.1 At the policy level, establish and improve the indicator system for energy conservation and emission reduction, and build a dynamic energy conservation supervision system.

Local governments at all levels should formulate various supporting measures and preferential policies to encourage energy conservation and emission reduction and promote the development of new energy, carry out publicity and education on the energy conservation of special equipment such as boilers, create a good working atmosphere, and improve the energy conservation and emission reduction of the general public. awareness of emission reduction, and jointly promote the energy saving and emission reduction of industrial boilers.

2.2 At the policy level, speed up the improvement of the laws and regulations system for energy conservation and emission reduction, and raise the penalty standards.

Relevant law enforcement departments should speed up the improvement of the laws and regulations system for energy conservation and emission reduction, raise the penalty standards, and focus on effectively solving the problems of low illegal cost and high law-abiding cost, so as to make the general public realize that fuel is a public resource and a scarce resource, which cannot be used arbitrarily. Vigorously save the use of fuel and put the fuel to practical use.

2.3 Promote frequency conversion technology with low power consumption at the technical level.

Because industrial boilers are manually adjusted by operators with their own experience during operation, the resulting waste of peak energy consumption is large. If the frequency conversion speed regulation technology can be used, the speed of the motor can be reduced, mechanical wear and tear can be reduced, and the working temperature of the motor can be reduced, thereby reducing the maintenance workload. At the same time, the motor adopts a soft start, and the starting current gradually rises from zero to the rated current value. In this way, it can not only save energy but also will not cause an impact on the power grid, greatly increasing the energy saving effect.

2.4 At the management level, establish and improve industrial boiler regulations and standards, and form a consensus on energy conservation and emission reduction in the whole society

Relevant industry leaders should seek innovative breakthroughs in management, so that management can become the soft power of industrial boiler energy conservation and emission reduction, and relevant national policy departments should establish and improve my country's industrial boiler fuel policies, energy-saving products, energy efficiency labels and other layers. Regulations and standards, so that the energy saving and emission reduction work of industrial boilers is established in a good environment under the supervision of the whole society, and finally a consensus on energy saving and emission reduction in the whole society is formed.

2.5 Improve the professional moral quality of technical personnel in the industry, and guide the energy saving and emission reduction of industrial boilers with innovative technologies.

We want to improve the technical quality and professional ethics level of our industrial boiler operators, and conduct comprehensive and systematic technical training and learning for industrial boiler operators, so that they can fully and effectively master the operation skills of industrial boilers and the corresponding maintenance of industrial boilers method.

3. Summary

Industrial boilers are accompanied by the development of my country's industry. Nowadays, people gradually realize that industrial boilers have low energy utilization rates and serious pollution, which do not meet my country's current requirements for energy conservation and emission reduction. Therefore, it is necessary to transform the problem of industrial boilers. It is necessary to carry out from 5 aspects at the same time. First, strengthen the quality management of personnel. Second, transform the structure of the boiler itself and improve the corresponding quality at the same time. Third, make a scientific calculation on the relationship between fuel and boiler, find the energy suitable for different boiler equipment, and achieve the purpose of reducing energy waste and protecting the environment. fourth. Modify the corresponding auxiliary equipment to make it more conducive to the operation of the boiler. Fifth, use effective control and management methods to help the boiler maximize its production capacity.
