Steam and hot-water biofuel-fired boilers

Advantages of steam and hot-water biofuel-fired boilers:

• Boilers designed for combusting two types of fuel: biofuel (sunflower seed husks) and natural gas, shifting from one fuel to the other without boiler shutdown.
• Rated output with production of steam at the rated parameters is ensured when burning either fuel (waste husks or natural gas).
• The boiler combustion chamber is not equipped with heavy mechanical components, increasing the operating reliability of the boiler as a whole and reducing maintenance and repair costs.
• Boilers are supplied for operating pressures up to 4 MPa.
• Boilers are fully automated, including a heating area cleaning system. This enables operating them without output decreases for cleaning. Thus, the annual steam production in a boiler significantly exceeds that made in boilers requiring periodic manual cleaning. The boiler operation is only interrupted for mandatory breaks within the company operating process.
• The large vertical cooling chamber (combustion chamber) makes it possible to cool even the ashes to a solid state, reducing clinging of soft particles on heating surfaces, while attaining a high heat exchange efficiency.
• Free access to the heating surfaces is ensured due to their design layout, significantly facilitating inspection and repair while in operation.
• The use of modern cleaning devices (blowing devices) makes it possible to reduce the temperature of waste gases behind the boiler to 150-160°С, increasing the gross efficiency of the boiler.

The stepped (four-step) blown air feed circuit to the combustion area (unlike the stechiometric production of fuel-air mixture) helps combustion at a relatively low temperature around 1100-1200°С and ensures sufficient stability of the combustion
