Heat and power engineering, specifically being heating devices includes a pyrolysis boiler, in which, wood is subjected to high-temperature gasification and pyrolysis with subsequent burning off of pyrolysis gases. A stable and controllable gasification of wood with a natural high moisture content is achieved, and at the same time, a highly efficient transfer of combustion heat to a liquid heat-transfer agent is obtained. A gasification chamber is positioned between two compartments of a pyrolysis gas combustion chamber of the pyrolysis boiler, while the external wall of the combustion chamber is used as a heat-transfer surface, and at the same time, neither the fuel bunker nor the gasification chamber are in contact with water.

A booster burner of the present disclosure basically has a burning unit, an air blower disposed at a rear end of a burning chamber of the burning unit and a high-pressure gas providing unit; wherein the burning unit has a fuel bucket for storing fuel and a burning chamber having a tubular shape, interior of the burning chamber has at least one nozzle, at least one fuel tube coupled to the fuel bucket is disposed at each the nozzle; and the high-pressure gas supplying unit has a gas storage bucket for storing high-pressure gas, each the nozzle is installed with a high-pressure pipe coupled to the gas storage bucket. Through the high-pressure gas, the slight atomization and acceleration effect is applied to the fuel which enters the nozzle, such that fuel molecules are refined and more completely burned, and the objective of increasing the fuel burning efficiency is achieved.

A method is provided for controlling airflow into a furnace that employs a velocity type damper. In one embodiment, the method for controlling airflow may include engaging a velocity type damper to an air port opening of a furnace. The velocity type damper includes at least one air controlling surface that is positioned proximate to a wall of the furnace at the air port opening so that air velocity exiting the at least one air controlling surface is substantially equal to the air velocity entering the air port opening to the furnace. The method may further include adjusting a cross sectional area through the velocity type damper to control air velocity into the furnace through the air port opening.

A fuel-operated vehicle heater, combustion chamber assembly unit includes a combustion chamber housing (14) having a combustion chamber bottom (18) and a combustion chamber circumferential wall (16) extending in a housing longitudinal axis (L) direction to define a combustion chamber (20). A porous evaporator medium (60) is on the combustion chamber circumferential wall or/and the combustion chamber bottom, at an inner side facing the combustion chamber. A fuel feed line (62) feeds liquid fuel into the porous evaporator medium. A first combustion air feed device (68), associated with the combustion chamber bottom, feeds primary combustion air (VP) into a first combustion zone (50) at which the porous evaporator medium is arranged. A second combustion air feed device (70), following the first combustion zone in the housing longitudinal axis direction feeds secondary combustion air (VS) into the combustion chamber at an axially spaced location from the first combustion zone.
