The fireplace includes a hearth suspended on a support. The hearth is defined laterally by a peripheral wall that is equipped with at least one combustion air inlet. There is a discharge pipe for discharging the combustion gases, that includes a bottom portion secured to a top part of the hearth, and a top portion opposite the bottom portion. The fireplace also includes at least one combustible fluid burner that is arranged in the hearth opposite at least one air inlet and a combustible fluid supply column that extends between a first end connected to a combustible fluid source and a second end connected to at least one burner. The supply column passed down through the discharge pipe from its top portion to its bottom portion and opens in the hearth in order to convey the combustible fluid from the combustible fluid source to at least one burner.

A gas-fired burner adapted for use on a liquid fuel. A method for essentially smokeless start-up and steady state operation of a gas-fired burner on a liquid fuel. The apparatus integrates a catalytic liquid fuel reformer with a flame burner designed for operation on a gaseous fuel of high Wobbe Index, e.g., natural gas. The method involves reacting a mixture of a liquid fuel and oxidant in a catalytic reformer to obtain a gaseous reformate having a low Wobbe Index; and thereafter combusting the gaseous reformate, optionally augmented with liquid co-fuel and oxidant, in the gas-fired burner under diffusion flame conditions. The invention allows commercial gas-fired appliances to be operated on a liquid fuel, thereby offering advantages in logistics and camp operations.
