May's cutting-edge technology trends and the latest guide to operation and maintenance manageme

1. Highlights of boiler technology innovation in May

Upgrade of high-efficiency and low-nitrogen combustion technology
The new water-cooled premixed burner has been put into commercial use. By optimizing the fuel-air mixing ratio, it can achieve nitrogen oxide (NOx) emissions below 30mg/m³, which is 40% lower than traditional technology.
Flue gas recirculation (FGR) technology combines AI algorithms to dynamically adjust the circulating air volume, adapt to load fluctuations, and take into account energy saving and environmental protection.
Hydrogen mixed-firing boiler pilot promotion
The first 35MW natural gas-hydrogen mixed-firing boiler in China has completed testing in the chemical park, with a hydrogen blending ratio of 20% and a 7% reduction in carbon emissions, providing technical verification for energy transformation.
Smart boiler system iteration
The digital twin-based boiler life cycle management platform has been launched, integrating sensors, edge computing and cloud analysis, achieving a fault prediction accuracy of 92% and a maintenance cost reduction of 25%.

2. New regulations on boiler safety and operation and maintenance in May

Safety standards strengthened
The State Administration for Market Regulation issued the "Technical Regulations for Boiler Safety (2024 Revised Edition)", which clearly stated that the calibration cycle of overpressure interlock protection devices was shortened from 1 year to 6 months, and the coverage of flaw detection of pressure-bearing parts was increased to 100%.
New requirements for energy efficiency management
The "transient response efficiency" indicator was added to the energy efficiency test of industrial boilers, requiring the efficiency fluctuation of boilers to not exceed 3% when the load suddenly changes (±30% rated load), promoting the research and development of dynamic energy-saving technologies.
Environmental protection supervision is becoming stricter
Many places have launched the pilot project of "ultra-low emission + carbon monitoring" for boiler flue gas, requiring the installation of online monitoring equipment to upload CO₂ emission data in real time, and enterprises that exceed the standard will face daily fines.

3. Insights on boiler market trends in May

Regional policies drive demand
In the final stage of the "coal to gas" in the north, the purchase volume of small gas boilers surged by 60% year-on-year, but some regions turned to biomass boiler transformation due to rising gas prices.
Export market differentiation
Orders in Southeast Asia have grown significantly, and Chinese boiler companies have occupied more than 30% of the local market share with their cost-effective advantages; the European and American markets have tightened carbon tariff policies and increased technical barriers.
Service model innovation
The "Boiler-as-a-Service" (BaaS) model has emerged. Companies have reduced users' initial investment through leasing + energy efficiency sharing models, and promoted the transformation rate of old boilers.

4. Industry experts' suggestions

Technology selection: For new projects, it is recommended to give priority to hydrogen mixed combustion or full premixed combustion technology to avoid future environmental protection policy risks.
Operation and maintenance optimization: Establish a "health file" for boilers, use big data analysis to develop personalized maintenance plans, and avoid excessive maintenance.
Policy response: Pay close attention to local carbon quota allocation rules, plan carbon asset management in advance, and reduce compliance costs.
