Overview
Industrial Solid Mixed Fuel Thermal Boiler with Pyrolysis Series "KD" is designed for the production of biomass pellets, offering efficiency and reliability in operation.
Industrial thermal boiler using mixed solid fuel with pyrolysis is an advanced heating system that utilizes staged combustion of solid fuels to achieve high efficiency and low emissions.
Main features:
Mixed solid fuel – can use wood chips, pellets, briquette pastilles, agro-pellets from biomass waste.
Pyrolysis technology – thermal decomposition of the fuel in low-oxygen conditions, generating a flammable gas that burns separately for better efficiency.
High efficiency – reaches 90-95% due to complete combustion of the resulting gases. Low emissions – combustion processes are optimized to reduce pollutants.
Advanced automation – thermal boilers are equipped with sensors, dampers, and electronic control for optimizing fuel consumption.
Advantages:
✔️ Reduced fuel costs by utilizing local biomass.
✔️ Increased energy efficiency through staged combustion technology.
✔️ Lower ecological impact compared to conventional solid fuel boilers.
Industrial thermal boiler using mixed solid fuel with pyrolysis Series "KD" are structurally assembled so that the combustion gases are used to create the drying environment, which are subsequently filtered with the help of a centrifugal cyclone and an electrostatic filter. They are designed for distributing warm air throughout the system, where it is possible to dry using filtered combustion gases. With this version, temperatures of up to 480-500 °C can be achieved, exceptionally up to 550 °C for drying non-flammable materials. Boiler Series "KD" can be used to dry raw materials such as sawdust and other substances that can tolerate higher temperatures for drying.
