The DZL series coal fired hot water boiler is a single-drum, horizontal chain grate boiler designed for efficient and stable hot water supply. It adopts a quick-assembly structure, allowing convenient installation, compact layout, and reliable long-term operation. Equipped with an advanced chain grate combustion system, the boiler ensures uniform coal feeding and sufficient combustion, improving thermal efficiency while reducing fuel consumption. A rear economizer is installed to recover flue gas waste heat and enhance overall energy utilization. The boiler features complete automatic control and safety protection systems, providing safe, stable, and energy-efficient operation. It is widely used for district heating, greenhouse heating, hotels, hospitals, schools, and industrial heating applications.

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)
