  We develop a method of theoretically investigating the charge, energy and
heat transport in the presence of the charge Kondo correlations. The Coulomb
blockade oscillations of heat conductance in the single electron transistor
exhibiting the charge Kondo effects are investigated. We explore the Wiedemann
Franz ratio in both charge-single channel and charge-two channel Kondo regime.
The close connections of our findings with the recent experiments on
multi-channel charge Kondo effects are discussed.
