Dall Energy have developed a biomass combustion system, featuring many improvements compared to state of the art technologies
A biomass plant can be subdivided into three main sub systems:
• Furnace (converting fuel into clean hot fluegas and ash)
• High temperature cooling (dry cooling of flue gas)
• Low temperature cooling (wet cooling of flue gas, utilizing condensing energy of water wapoers)
| Each subsystem has been redesigned and optimized for
• High efficiency
• Low emissions • Low maintanancen
• Easy to produce
• Easy to transport
• Easy to install
• Fuel and product flexible
|  | | Multi fuel and multi purpose
The oven is developed in order to optimize fuel flexibilitiy and to reduce emissions, maintenance costs and investment costs.
The high temperature cooler can heat thermal oil.
By using thermal oil the energy from the high
temperature cooler can generate:
• Power, by use of ORC machines
• Cooling, by use of absorption chillers
• Clean water, by use of vacuum distillation
• Steam, by using thermal oil-steam boilers
• District heating.

The energy of the flue gas is recovered in a condensation unit. Condensation units are known in energy plants, but Dall Energy units are unique: -
Due to the high moisture content and the high water dew point in the flue gas, the amount of energy produced in the condensation unit is much higher compared to traditional condensation units; -
Due to the high water dew point, the condensation unit can produce district heating water at much higher temperatures than normal condensation units: -
Due to the air moisturizing system, the flue gas is cooled to about 35°C resulting in very little fume and a very high energy efficiency of the plant.
Our biomass plants are manufactured and installed by SEM steelindustry SEM Steelindustry a/s has more than 30 years experience of manufacturing a wide range of machinery and components to the industry. Production equipment, semi- and fully automatic machinery and batch production are some of the fields SEM Steelindustry have great experience within.
Besides biomass combustion plants SEM Staalindustri a/s is subsupplier to Danish; power plants and the environmental sector including waste incenerators both in Denmark and abroad
