FangKuai Maintains NOx Below 10 mg/m³ After 5,000 Hours of Operation

Under increasingly strict environmental standards and the global push toward carbon reduction, industrial enterprises are facing greater pressure to control emissions while maintaining production efficiency. For many factories, failure to meet emission requirements can mean project delays, production shutdowns, fines, or even wasted investment.

FangKuai Boiler has once again proven that ultra-low emissions and high energy efficiency can be achieved at the same time.

Recently, two industrial boiler projects in Hebei Province have been operating stably for nearly one year, with a total runtime exceeding 5,000 hours. The test results show that the NOx emissions of all boilers remained consistently below 10 mg/m³, fully meeting the strict environmental requirements in Handan and the wider Beijing-Tianjin-Hebei region.

Stable Steam Supply for an Electroplating Industrial Park

One of the benchmark projects is located in an electroplating industrial park in Hebei. The project includes 9 gas-fired steam boilers in total: one 4-ton boiler, one 6-ton boiler, and seven 10-ton boilers.

These boilers provide high-temperature steam for electroplating, hot-dip processing, and other surface treatment processes within the industrial park.

The electroplating industry has high requirements for steam quality. Stable and clean steam is essential to ensure coating uniformity, adhesion quality, and continuous production. With its high-efficiency heat exchange system and precise temperature control technology, FangKuai Boiler provides reliable thermal energy support for the production lines.

Reliable Operation for a Textile Printing and Dyeing Project

Another project is a textile factory in Hebei, equipped with one 10-ton gas-fired steam boiler.

In textile printing and dyeing, steam pressure stability directly affects fabric quality. Pressure fluctuations may lead to uneven dyeing, poor setting results, and production losses.

FangKuai’s 10-ton steam boiler provides stable steam output and accurate pressure control, helping the textile production line maintain continuous and efficient operation.

NOx Emissions Below 10 mg/m³: Long-Term Stability Matters

The most important achievement is not only that the boilers met the emission standard once, but that they maintained ultra-low NOx emissions during long-term operation.

After nearly one year of operation, all boilers in both projects have maintained NOx emissions below 10 mg/m³. This demonstrates FangKuai’s real environmental strength: not temporary compliance, but long-term stable performance.

For industrial users, this means lower environmental risk, stronger production continuity, and greater confidence in future project operation.

High Efficiency and Lower Operating Costs

FangKuai Boiler does not only focus on ultra-low emissions. Energy efficiency is another key advantage.

The boilers adopt fully premixed low-NOx combustion, FIR flue gas recirculation, and a high-efficiency condensing heat exchange system. Compared with traditional boilers, the thermal efficiency can be significantly improved, reaching over 98%.

Taking a 10-ton gas-fired steam boiler as an example, the fuel cost savings can reach hundreds of thousands of RMB per year. When combined with FangKuai’s intelligent cloud control system, users can also achieve remote monitoring, automatic adjustment, and reduced labor costs.

Cleaner Steam, Lower Energy Consumption

Under the pressure of strict “10 mg” emission standards, FangKuai Boiler helps industrial enterprises pass environmental inspections while reducing real operating costs.

These two benchmark projects prove that clean combustion, stable operation, and energy-saving performance can be achieved together.

FangKuai Boiler will continue to provide high-efficiency, low-emission industrial boiler solutions for manufacturing enterprises, helping every unit of steam become cleaner, more efficient, and more valuable.
