Abstract: A burner for pulverized coal has a coal duct (1) for pulverized coal and primary combustion air and a secondary combustion air duct (2) such that the coal and primary air and secondary air mix outside the outlet nozzles of the duct in a mixing zone at which combustion occurs. Coal distribution means (7) in the coal duct create, adjacent the outlet nozzle, at least one outer zone of flow spaced from the coal duct axis and at least one inner zone of flow nearer the coal duct axis. There are means (12) for slowing flow in the outer zone relative to the flow in the inner zone, prior to the mixing zone. To achieve good mixing, and promote NO x  reduction, the coal concentration in the outer zone is higher than in the inner zone. The slowing means (12) may be radially inwardly projecting baffles.

Abstract: An amplifier circuit has an amplifying transistor (Q₁) having its emitter directly grounded and a biasing transistor (Q₄) for supplying a bias current to the base of the amplifying transistor through its emitter. The biasing transistor receives at its base an output voltage generated and forwarded from a bias voltage generating circuit which is composed of a constant current source (7), a constant current transistor (Q₂) and another biasing transistor (Q₃). One bias voltage generating circuit may provide its output voltage commonly to a plurality of biasing transistors each associated with the amplifying transistor. The circuit makes it possible to have the amplifying transistor operate at a desired operation point without using a resistor having a high resistance value. Further, since the emitter of the amplifying transistor is directly grounded, both the noise figure characteristics and high frequency characteristics are improved.
