Adopting the mature CWNS direct‑heating structure, this horizontal three‑return atmospheric hot water boiler consists of a boiler shell, furnace tank, reversal chamber, front & rear smoke boxes and fire tubes. Its large‑diameter corrugated furnace tank strengthens heat transfer and improves thermal efficiency significantly. The wet‑back flue gas structure avoids common corrosion risks caused by high‑temperature flue gas scouring of rear smoke boxes, ensuring long‑term safe operation. Multiple control systems including touch‑screen, PLC and conventional electric control are optional to meet diverse intelligent management demands.
With modular design, the boiler greatly cuts on‑site installation work and avoids operational risks from improper installation. Under normal atmospheric pressure, it supplies stable heat without complex pressure‑bearing inspection procedures, featuring high construction efficiency and low maintenance costs. The furnace water acts as thermal medium without external circulation, and low‑temperature return‑water prevents flue‑gas corrosion from low‑temperature exhaust, extending service life.
Weifu Boiler has rich experience in supplying hot water equipment for public buildings, gymnasiums, commercial complexes and municipal facilities. The Jiangyan Gymnasium project marks another typical public‑service benchmark, demonstrating our reliable product quality and one‑stop thermal‑energy solutions for large‑scale domestic hot water scenarios.
In the future, WEIFU Boiler will keep optimizing energy‑saving, low‑carbon and safe boiler technologies, empowering more public‑welfare and commercial projects with high‑performance heating equipment, and contributing to urban public infrastructure upgrading.
