  • Patent number: 10371377
    Abstract: A burner assembly combines oxygen and fuel to produce a flame. The burner assembly includes an oxygen supply tube adapted to receive a stream of oxygen and a solid fuel conduit arranged to extend through the oxygen tube to convey a stream of fluidized, pulverized, solid fuel into a flame chamber. Oxygen flowing through the oxygen supply tube passes generally tangentially through a first set of oxygen-injection holes formed in the solid fuel conduit and off-tangentially from a second set of oxygen-injection holes formed in the solid fuel conduit and then mixes with fluidized, pulverized, solid fuel passing through the solid fuel conduit to create an oxygen-fuel mixture in a downstream portion of the solid fuel conduit. This mixture is discharged into a flame chamber and ignited in the flame chamber to produce a flame.

  • Patent number: 10365040
    Abstract: A method for drying high moisture, low calorific value lignite for a generating set and recovering water contained therein and an apparatus thereof mainly consist of a rotary steam tube dryer, a washing cooling tower, a coal mill, a first bag filter, a condenser, a weighing surge bunker, a water ring vacuum pump and so on. A drying system is integrated with a milling system, every dryer and the corresponding coal mill are disposed and are directly connected via a surge bunker, thereby not only saving the heat lost during the transportation of pulverized coal, but also omitting a long-distance transportation from a conventional drying system to a conventional milling system, effectively avoiding such phenomena as dust pollution, waste and spontaneous combustion during transportation and transshipment, simplifying the coal preparation system employed in the front-end process of drying.

  • Patent number: 10364985
    Abstract: A bio-fuel furnace for use in waste management, non-combustible particulate collection and useable energy production. The bio-fuel furnace includes a combustion unit, a particle separator, an airflow management system. The combustion unit includes a modular ceramic core of stacked cylindrical sections, which store thermal energy. The stacked core sections form an internal combustion chamber and an expansion chamber. The airflow management system regulates airflow through the combustion unit and the particle separator forcing super heated ambient air into the combustion unit and drawing exhaust air from the particle separator to precisely control both the combustion process and the storage of useable thermal energy. The airflow management system includes a series of preheat coils wrapped around the ceramic core, an inlet fan which forces ambient air through the coil into the combustion unit and an exhaust fan that draws exhaust air through the separator and from the combustion unit.
