Packaged Water-Tube Rotary-Grate Steam Boiler
The packaged water-tube steam boiler with a rotary grate is a safe solution that meets small- and medium-capacity steam needs in a compact, integrated unit. With its vertical water-tube design and stoker/rotary grate solid fuel system, it automatically processes coal and biomass and discharges ash automatically. Its firebrick and rock wool-insulated outer casing retains heat inside, maximizing efficiency. The boiler, which can be sized according to the facility’s physical conditions, stands out for its easy installation and simple maintenance.
Packaged Water-Tube Rotary-Grate Steam Boiler
The packaged water-tube rotary grate steam boiler is a compact redesign of header-type water-tube boilers; it was developed to meet small- and medium-capacity steam needs in a single integrated unit. Thanks to its structure consisting of vertically arranged water tubes, it offers much safer operation compared to fire-tube boilers.
The boiler’s most important feature is its ability to be coupled with either a stoker or a rotary grate solid fuel system, depending on the need. The rotary grate ensures continuous and balanced combustion by automatically feeding coal and biomass into the furnace, advancing the fuel throughout the combustion process, and automatically discharging ash. Flame passage rates are higher than in smoke-tube boilers; by using firebrick and rock wool mesh on the outer surface instead of a piping system, heat is retained inside and efficiency is maximized.
Depending on the steam capacity, there are one or two steam drums mounted on top of the boiler; steam is transferred to the process via these drums. Thanks to its modular design, the boiler can be sized to fit the facility’s physical conditions and stands out for its easy installation, simple maintenance, long service life, and safe operation.
