Why choose
Electric Heating Steam Boiler?

Condensing boilers are advanced solutions that boost energy efficiency by incorporating high-efficiency condensers and economizers to capture heat from exhaust gases. The design aims to utilize both sensible heat and the latent heat released by condensing water vapor, markedly improving thermal efficiency.

The system capitalizes on the large quantities of vapor produced during combustion, particularly from hydrogen-rich fuels like natural gas. By deploying a condenser, this vapor – along with its substantial latent heat – is condensed, recovering heat that would otherwise escape with the flue gases. This process not only conserves energy but also significantly reduces heat loss.

With this innovative technology, a low nitrogen condensing steam boiler could theoretically enhance the thermal energy usage rate by over 7.2%, translating into a near 10% savings in natural gas. This makes a condensing boiler's thermal efficiency of up to 105% not just achievable but scientifically substantiated, redefining efficiency benchmarks in heating technology.

Boiler Features

The adoption of a wet-back structure and an offset furnace with corrugated furnace allows for increased heating surfaces and greatly enhanced strength.
Boiler has a large heating surface, rapid temperature, and pressure rise, with simple operation.
Rational and compact structure, strong load adaptability, complete combustion, and high thermal efficiency up to 105%.
Condenser is made of high-quality sulfuric acid dew point corrosion-resistant steel, 09CrCuSb (ND steel), with spiral fin tubes that ensure a long service life.
Condenser is installed on the upper part of the boiler without occupying ground space, and the condensed water on the heat transfer surface can be naturally drained.
Complete with safety accessories, ensuring safe and economical operation.
Equipped with a high-quality, high-performance burner, providing stable and reliable combustion. Ultra-low nitrogen emissions can meet the strictest environmental standards.
High level of automation, which reduces the need for manual labor.
The boiler has a small volume, light weight, and occupies a small area, saving on infrastructure investment.
