Abstract:
In a system for providing coal/air flow to a coal fired power plant combustion chamber having an exhauster fan, a discharge chute and a riffle box, an apparatus for providing a homogeneous coal/air flow to the riffle box comprising:a first deflector surface located in the discharge chute downstream of the exhauster fan in a portion of the discharge chute corresponding to a heavy distribution of coal/air flow, and a second deflector surface located in the discharge chute, the second deflector surface being radially spaced from the first deflector surface, the second deflector surface further being located in a portion of the discharge chute corresponding to a light distribution of coal/air flow, the first and second deflector surfaces being angled radially inwardly in the discharge chute toward a convergent point in the discharge chute downstream of the first and second deflector surfaces to redirect the heavy and light distributions of coal/air flow to radially converge on one another in the discharge chute upstream of the riffle box, the first and second deflector surfaces further being spaced radially from the internal surface of the discharge chute.
