The DZL chain grate hot water boiler is a single-drum, horizontal quick-assembly boiler designed for efficient and stable hot water supply. It adopts an advanced chain grate combustion system, ensuring uniform fuel feeding, sufficient combustion, and reliable operation. The boiler features a compact structure with factory pre-assembly, allowing easy transportation and fast on-site installation. A rear economizer is installed to recover flue gas waste heat, improving thermal efficiency and reducing operating costs. Equipped with complete automatic control and safety protection devices, the DZL chain grate hot water boiler operates safely and efficiently. It is widely used in district heating systems, greenhouses, hotels, hospitals, schools, and industrial heating projects.

A thermal oil boiler is an industrial heating system that uses heat transfer oil instead of water or steam to deliver high-temperature energy safely and efficiently.
A 1 ton biomass steam boiler costs between $18,000 and $35,000 in 2026, while total installed project cost typically ranges from $35,000 to $75,000 depending on automation and configuration.
For a 4 TPH boiler, the total heat demand comes out to roughly: 4,000 kg × 2,750 kJ ≈ 11,000,000 kJ per hour (11 GJ/h)
