VHSB Series – Vertical Hybrid-Type Steam Boiler

VHSB Series – Vertical Hybrid-Type Steam Boiler

Single-drum water-tube steam boilers are efficient, durable steam generation systems developed for industrial processes requiring high pressure and high capacity. Their water-tube design enables rapid heat transfer, delivers high steam output and responds safely to sudden load changes.

The rotary grate (chain grate) combustion system used in these boilers enables the efficient combustion of coal, biomass and low-calorific-value solid fuels in particular. The continuously moving rotary grate ensures complete fuel combustion, delivering high efficiency, low ash formation and stable combustion. This is a significant advantage for facilities that require long-term, uninterrupted operation.

The boiler’s single-drum water-tube design rapidly transfers heat generated in the combustion chamber to the water. This minimizes energy losses and reduces operating costs. Its construction is optimized for long service life under high temperatures and pressures.

With its high efficiency, low emissions, durable construction and rotary grate combustion system, the single-drum water-tube steam boiler delivers outstanding performance in solid-fuel processes. It is an ideal solution for industrial facilities seeking energy efficiency and reliable steam generation.
