The fully premixed low-nitrogen condensing steam generator uses stainless-steel finned economizers to preheat feedwater and produce high-temperature steam within one minute. With no need for a pressure vessel, it directly generates steam through surface-combustion radiant heating, achieving thermal efficiency up to 99%. The system features continuously variable output, compact size, and distributed installation capability.

Working Principle

Using continuous steam transmission technology, the unit maintains stable and uninterrupted steam supply with minimal heat loss. Fully premixed surface combustion provides strong radiant heat, enabling instant steam generation. Intelligent computer control allows easy switching between steam, hot-water supply, and heating modes.

Water-vapor separation recycles moisture to ensure saturated steam output. Stepless variable-speed heating automatically adjusts burner output based on system load, maintaining optimal efficiency.

Features

Fully premixed surface combustion thoroughly mixes air and gas before ignition, ensuring complete combustion, high efficiency, and ultra-low emissions.

Key characteristics include:

High thermal efficiency, low CO, and significantly reduced NOx.

Short, uniform flame without high-temperature zones.

Lower combustion and flue noise.

Compact chamber design due to premixed flame characteristics.

Wide modulation range (100–15000 kW/m²).

Efficient radiant heat transfer at low loads.

Low thermal inertia with fast temperature response.

Safe operation with low tempering tendency.
