Abstract:
A boiler has a tank, a hearth contained in the tank, a gas pipe having one end in communication with a gas exit of the hearth and the other end passing through the hearth, a combustor in communication with a bottom of the hearth, and a fuel supply device being connected to a fuel inlet of the combustor.
Abstract:
Cooking and heating stove fuelled by pellet or biomass grain apt to cook and to heat water for domestic heating comprising a hearth fuelled by pellets or biomass grains, at least one plate to cook food and two heat exchangers to heat water for domestic heating wherein the cooking plate is located above the hearth fuelled by pellets or biomass grains, said two heat exchangers are positioned at the sides of the cooking plate, that on one side of said heat exchangers two inclined deflection plate are mounted that forces the combustion fumes to go up to touch the cooking plate and then to flow on the heat exchangers, the heat exchangers are two bundles with parallel pipes, on said pipes of said bundle heat exchangers at least one fixed deflection plate is located, said fixed deflection plates are perpendicular to said pipes of said bundle heat exchangers, each fixed deflection plate has a unique gateway that is positioned above or below each pipe bundle.
Abstract:
The present invention relates to a firewood boiler, comprising: a boiler main body including a feeding hole through which wood fuel and air for combustion are fed, a smoke exhaust hole defined in the top thereof so as to be connected to an exhaust pipe, an air inlet defined adjacent to the smoke exhaust hole, and a heating-water store in which heating water is stored; a main opening/closing unit installed on the boiler main body to open and close the feeding hole and selectively supply and block the entry of outside air into the boiler main body when the feeding hole is closed; an auxiliary opening/closing unit for supplying outside air into the boiler main body when the entry of outside air is blocked by the main opening/closing unit; a temperature sensor for sensing the temperature of the heating water; and a control unit for controlling the inflow and blocking of air by means of the main opening/closing unit on the basis of information on the temperature sensed by the temperature sensor. The heating water store is integrally formed along the entirety of the boiler main body, and the auxiliary opening/closing unit maintains a pilot flame for the wood fuel by supplying outside air into the boiler main body when the main opening/closing unit blocks the entry of outside air. Thus, a firewood boiler may be provided that can be safely used for a long period of time without extinguishing a pilot flame.
Abstract:
The present invention relates to a solid fuel and, more particularly, to a solid fuel boiler which uses, as a heat source, solid fuel including rice straws, fallen leaves, trees, etc. and can receive oil fuel and gas fuel so as to keep a fire alive.
Abstract:
A boiler including a water jacket surrounding upper and lower combustion chambers for receiving heat for heating water or other fluid therein, which chambers are defined by a refractory structure that extends entirely across the inner casing. A vertical passage through the refractory structure provides for flow of combustion gases from the upper to lower combustion chamber. Oxygen is provided through a first forced air inlet to the upper combustion chamber for burning of wood or biomass, and is provided through a forced air passage in the refractory structure and opening into the vertical passage thereby providing at least one second forced air inlet for burning of the combustion gases and particulates passing therethrough. The refractory structure sealingly engages the inner casing in a manner to seal the upper combustion chamber from the lower combustion chamber so that the upper combustion chamber can be made substantially air tight.
