A grill using a flue, of the present invention, can provide healthy food by allowing meat, fish and the like to be cooked without being burnt since high-temperature smoke, which is to be generated while firewood burns in the combustion chamber of a firewood combustion cylinder, is supplied to the inside of the flue chamber of a cooking hot plate, is guided along a smoke guide plate, and is simultaneously discharged to the outside through a smoke outlet, thereby slowly heating a cooking iron plate. In addition, support members fixed to the bottom surface are provided so as to be height-adjustable, thereby stably fixing the grill. Additionally, since an oil outlet is formed at the upper edge of the cooking iron plate, the oil to be generated during meat cooking is discharged to the combustion chamber of the firewood combustion cylinder so as not to remain on the cooking iron plate, and thus the present invention is sanitary and provides an ease of cleaning and the like.

A condensate neutralizer system for treating condensate of a condensate generating device, the condensate neutralizer system including a container having an inlet and an outlet, the inlet is configured to receive condensate from the condensate generating device, the container is configured to contain a condensate neutralizing material useful for treating the condensate and the outlet is configured to drain condensate treated with the condensate neutralizing material; a controller; and a pH meter functionally connected to said controller, the pH meter is configured to take pH measurements of the treated condensate, the measurements are configured to be compared to a fault pattern, wherein the fault pattern is defined by a condition where the pH measurements are lower than a pre-determined pH level and if a fault is determined to exist, a warning is raised or a delivery of replenishment of the condensate neutralizing material is initiated.

A pellet barbecue configured to recirculate exhaust gas, allowing for the reduction of oxygen in the cooking chamber. The pellet barbecue is configured with an exhaust gas recirculation system, and an angled bottom fire pot. The electric gas recirculation fan pulls gases from a gas recirculation channel, and blows it onto the angled bottom fire pot. The gas recirculation channel is equipped with a movable mixer flap to control how much of the gas pulled by the gas recirculation fan is exhaust gas or outside air. The pellet barbecue controller monitors the conditions in the cooking chamber, and controls the gas recirculation fan speed and positioning of the mixer flap to maintain a desired temperature, while optimizing the concentration of wood taste compounds from the pellets in the cooking chamber.

A method for producing a component with a predetermined gloss level, including the steps of: preparing a component with a metallic surface; producing a matte/glossy mixture by mixing glossy paint and matte paint in a predetermined mixing ratio; applying the matte/glossy mixture to the metallic surface of the component; and cross-linking the matte/glossy mixture.

An outdoor cooking system having an elongated horizontal chamber, a vertical chimney that covers a portion of the chamber, and a frame that supports the chamber. The vertical chimney has an inner wall that has an opening that is in communication with the chamber and permits that coals to be easily transferred from the chimney and spread out within the chamber.

A solid pellet fueled heater having a base unit with forced air blowers and a dual tube chimney structure is disclosed. The dual tube chimney structure may be used to warm incoming air for distribution around the heater. The pellet heater may also include a dual auger system and multi/high speed auger motor. The dual auger may include first and second auger blades mounted on a single auger shaft having blade pitches configured to convey solid fuel in opposite directions.

Apparatuses for burning a burnable fuel source, and methods of operating the same, are disclosed. The apparatuses may include a housing defining a chamber and a tube extending through the housing and disposed at least partially within the chamber of the housing, the tube accommodating a burnable fuel source. A tray may be disposed within the chamber and accommodating at least a portion of the burnable fuel source when received within the tube. A refractory brick may be disposed on at least a portion of the tray, and a plurality of pipes may be disposed within the housing such that, upon actuation of the apparatuses, heat from the burnable fuel source contacts the plurality of pipes. The apparatuses may also include an air outlet in the first housing configured to allow air from within the chamber to exit the chamber.

A solid fuel heating apparatus (1) comprising a combustion chamber provided with a glass door (4) opening to the outside, an intake device (11) for the intake of outside combustion air into said chamber, an outlet duct for the burnt gases (2) and a sealed preheating enclosure for preheating the combustion air, conveying said air to the combustion chamber, connected at a first end to the intake device (11) and ending at a second end with a plurality of openings (9) releasing the air preheated by the preheating enclosure into the combustion chamber, characterized in that the preheating enclosure consists of a set of sealed heat exchanging pipes containing the combustion gases and the burnt gases (3, 8, 12, 15, 17, 18, 19), ending with the abovementioned openings (9), which are variable in size and are arranged in such a way as to modulate the flow of preheated air released into the chamber, enclosing the flame and combustion area in the natural conical shape of said chamber.
