FIELD: power industry.
SUBSTANCE: flameless petroleum heater includes the following components: oxidation channel and fuel channel having multiple centralisers attached to external wall of fuel channel in which at least one centraliser or a section of centraliser is inclined relative to longitudinal axis of fuel channel. At least one centraliser is inclined by not less than 90° relative to longitudinal axis of fuel channel. At least one centraliser is bent so that at least a section of centraliser is inclined relative to longitudinal axis of fuel channel. All centralisers or the majority of them is inclined relative to longitudinal axis of fuel channel. Centralisers are made from material that is different from material of wall of oxidation channel. Centralisers are coated with material differing from wall material of oxidation channel. Centraliser has triangular shape.
EFFECT: invention allows improving fuel and air mixing, reducing or avoiding maximum temperatures, and helps preventing collision of fuel with inner surface of oxidation channel.
