The SZL series coal fired steam boiler is a double-drum, horizontal chain grate boiler designed for efficient combustion of various types of coal. It adopts a modular assembly structure, providing convenient installation, stable operation, and high reliability. The boiler uses a chain grate combustion system to ensure uniform fuel distribution and sufficient combustion. A rear economizer is installed to recover flue gas waste heat, improving thermal efficiency and reducing fuel consumption. Equipped with complete control and monitoring instruments, the SZL series coal fired boiler ensures safe, stable, and efficient operation. It is widely applied in food processing, textile, chemical, pharmaceutical, and industrial manufacturing industries.

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)
