Water cooled vibrating grate

DP CleanTech’s water cooled vibrating grate was developed and designed specifically for the combustion of biomass fuels and has proven to be the best combustion system for herbaceous and woody fuels.

Improved availabilityThe water cooled vibrating grate is one of the most reliable combustion grates in the world. The vibration inhibits the formation of large slag particles, liable with straw and waste wood fuels, which makes it suitable for burning fuels with high slagging and sintering propensities. Another advantage is the vibrating equipment has less moving parts than moving grates and thus requires less maintenance.

Improved efficiencyThe vibration movement and air distribution system optimizes the combustion process evenly across the grate. The fully automated system is one of the contributing factors to DP CleanTech achieving boiler efficiencies of 90-92%.

Wood fired technology

Wood chip biomass can serve as an excellent fuel for energy production and DP CleanTech has developed its technology to optimize its potential. Woody fuels tend to have higher moisture contents and therefore offer opportunities for further recovery of heat through flue gas condensation. In suitable circumstances DP CleanTech’s condensing scrubber has boosted boiler efficiencies to 101%.

Improved fuel flexibilityThe vibrating grate is one of few grates able to deal with woody and herbaceous biomass fuel mixtures.

22 23

DP CleanTech has developed its own specific boiler island technology to serve the rapidly growing waste to energy market. The technology is also easily adapted to many forms of process residue.

The Step GrateSFA’s step grate is the only completely flat combustion grate in the world.

Improved fuel flexibilityAlthough capable of low density high calorific fuels like wheat straw, the Step Grate is an extremely efficient combustion platform and ideally handles more difficult fuels like waste wood, peat and municipal solid waste. The step grate is even able to handle metals with low melting points such as aluminum (tin foil, bear cans, etc.) or zinc (galvanized nails, etc.) which may cause problems for the vibration grate.

Improved availabilityThe Patented water cooled grate plates are used for problematic fuels with a calorific value greater than 12 MJ/kg, this allows our customers to achieve extended grate lifetimes.

Mixed fuel

DP CleanTech understands the importance of securing a reliable fuel supply and has focused much o f i t s r esou rces on p rov i d i ng technologies that help mitigate this potential problem. Mixed fuel power plants offer greater flexibility and lowers dependence on one single fuel. However, when mixing fuels the variations in properties such as moisture content, ash content and fusion temperatures pose increased chal lenges to secur ing opt imal performance and require further

modifications to the boiler design. Many of DP CleanTech’s power plants are designed to handle multiple fuels and we have developed a rich experience in building custom designed integrated mixed fuel power plants which convert waste residues into steam at specified output for the production of heat and electricity.
