Renewable thermal energy is a fast growing sector where production and treatment processes are constantly improving. Changes in unit capacities and processes result in new challenges for operators, energy companies and plant designers.
Our solutions integrate renewable thermal energy production, treatment, distribution and conversion units.
Howden products and services offer the best long-term value across a wide range of renewable sector applications, ensuring consistent, safe and efficient site output.
Our blowers gather landfill gases for collection and transfer to treatment units. Our fans, blowers or screw compressor collect biogas generated in anaerobic digesters. Howden heaters, draught fans and air fans are used to increase efficiency of biomass, wood and waste boilers.
Screw compressor feed biogas treatment units while bio-methane screw compressors deliver gas to the grid or gas turbines to the appropriate pressure.
Howden fans extract residual gases from process capacities and ensure buildings ventilation and aeration. Cooling fans are used in HVAC and for refrigeration applications
We provide Steam Turbine solutions for all customer demands - from the simple CORE for packagers, up to extensively customised/engineered systems within the range up to 40 MW. The most economical and flexible turbines that you can get.
Direct Heat and Power CHP : Electricity-Fuel gas. In site power plant equipments compress the feed gas for the turbines to the appropriate pressure.
Gas contains methane and carbon dioxide. Landfill gas is collected and sent to the gas treatment unit.
If biomethane is being fed to grid there may be a requirement for a biomethane compressor
BioMethane Compressed gas – vehicle fuel & distribution.
The biogas is first compressed, then cooled and desulphurized. A large plant may have 2 stages of biogas compression (up to 3 units – up to 11 bar).
Typically there will be 2 biogas compressors feeding the absorption column. If biomethane is being fed to grid there may be a requirement for a biomethane compressor
Membrane separation 1 or 2 compressor according to capacity
Storage compressors, High pressure diaphragm compressors and Hybrids.
In site power plant equipments compress the feed gas for the turbines to the appropriate pressure.
Shorebased wave systems (Wells turbines)
Forced draught fans move ambient air at low pressure through the air preheater to provide heated oxygen for the combustion process.
Induced draught fans are vital in maintaining furnace pressure at just below atmospheric pressure. They draw the ﬂue gases out of the boiler into the air preheater.
Primary air fans are used to move air through the air preheater in coal and biomass fuelled stations. The size and conﬁguration of the fan depends on the temperature of the primary air.
Secondary air fans feed into the boiler combustion chamber at a higher point than the primary air to promote more complete combustion.
