  We develop a conformal-field theory approach for investigation of the quantum
charge-, heat- and thermoelectric- transport through a quantum impurity fine
tuned to a non-Fermi liquid regime. The non-Fermi-liquid operational mode is
associated with the overscreened spin Kondo effect and controlled by the number
of orbital channels. The universal low-temperature scaling and critical
exponents for Seebeck and Peltier coefficients are investigated for the
multichannel geometry. We derive and analyze the universal dependence of the
thermoelectric coefficients on the number of orbital channels. We discuss the
universality of Lorenz ratio and power factor beyond the Fermi Liquid paradigm.
Different methods of verifying our findings based on the recent experiments are
proposed.
