　　What are the technologies for retrofitting coal-fired boilers? Which is better, biomass boiler or gas boiler, and what is the prospect?

　　According to national policy requirements, coal-fired boilers need to be retrofitted. So, what are the technologies for retrofitting coal-fired boilers? We have invited experts from relevant departments to answer this question for everyone.

　　At present, the main methods of transformation include raising emission standards, "coal to gas", "coal to biomass", etc. So what are the situations of these three transformations

　　1. The upgrading and renovation mainly targets large power plant boilers and large industrial boilers with a capacity of over 20 tons. This renovation can improve the boiler emission standards, but the investment cost is also relatively high. Moreover, the major problem is that the national emission standards are being raised every year, and it may not be possible to meet the standards this year. This results in continuous renovation and investment by enterprises.

　　2. Coal to gas "is a new type of energy advocated by the government. Natural gas is convenient to use, clean and environmentally friendly, but the disadvantage is that compared with coal, the cost increases by 2 to 3 times, and the acceptance of enterprises is not high. In addition, coal-fired boilers cannot be retrofitted with gas-fired boilers, and new gas-fired boilers need to be built, which is a considerable investment. In addition, pipeline fees and account opening fees need to be paid. Generally, a 10 boiler requires a complete investment of 2 to 3 million yuan, and the cost of retrofitting is significant. Speaking of the operation after the renovation, there are mainly problems. Firstly, the operating cost is 2 to 3 times that of coal. Secondly, during peak gas consumption periods, especially in winter, priority is given to meeting the gas needs of residents, resulting in many enterprises not being able to meet their gas pressure requirements, thereby affecting their production.

　　3. Based on the above, we have discovered a new type of energy biomass fuel that can meet the needs of low investment transformation and run the economy. It is also a type of biomass energy fuel that our country actively advocates and encourages the use of clean energy and high efficiency. At the same time, the country has introduced multiple policies to encourage the development and use of clean energy. Furthermore, biomass clean fuels are increasingly favored in society.

　　What are the technologies for retrofitting coal-fired boilers? Which is better, biomass boiler or gas boiler, and what is the prospect?

　　This indicates that the prospect of transforming coal-fired boilers into biomass boilers is getting better and better, mainly because:

　　1. Widely sourced China is a large agricultural country, producing a huge amount of crop straw, agricultural and forestry waste every year. In addition, China has vast forest resources, and the waste from wood processing is a good raw material for biomass fuel.

　　??????

　　2. Low investment cost and low operating price. Before the development and utilization of these biomass clean fuels, their raw materials were all waste, with some being buried and some being incinerated. The current development and utilization have brought economic benefits to the vast agricultural population, with the use of this fuel saving 30% -60% of costs compared to fossil fuels. In addition, our company has developed a new renovation method, which means that the cost of renovating a 10 coal-fired boiler will not exceed 500000 yuan, saving 6% of the investment compared to gas boilers. The operating cost is half of that of gas boilers.

　　??????

　　3. Clean and environmentally friendly. Biomass pellet fuel is a nationally recognized clean energy source, and the waste generated during combustion meets the national emission standards, resulting in minimal environmental pollution.

　　??????

　　4. Large dosage. Nowadays, biomass fuel power plants are being built around our lives. Taking Hunan as an example: 19 are under construction, 7 have been built, and these 7 alone consume over 1.4 million tons of biomass fuel annually. What about the whole country! And our company's current annual output of 500000 tons is sufficient to meet the demand for small industrial boilers.
