Gas-fired burner having porous ceramic face through which gaseous combustion mixture emerges and on the emerging surface of which the mixture burns, can heat substrate with help of streams of air or recycled combusted gas sweeping across substrate to help remove moisture or other volatiles being driven from substrate. Burner body can have pilot ignition compartment. Ceramic face can be large ceramic fiber mat the back of which is supported to burner body back. Combustion mixture can be controlled to essentially stoichiometric.
