Abstract

The invention discloses a multi-return gas boiler, comprising a housing, a heating device arranged in the housing, and a water storage space formed between the heating device and the housing. The shell comprises a water inlet, a smoke exhaust, and a steam outlet located at the top of the shell. A heat device includes a combustion chamber dispose at that bottom of the housing, a first cigarette collecting box located above the combustion chamber, a second cigarette collecting box located between the combustion chamber and the first cigarette collecting box, a third smoke collecting box locatedabove the first smoke collecting box, wherein the combustion chamber is communicated with the first smoke collecting box through a first pyrotechnic pipe, the first smoke collecting box is communicated with the second smoke collecting box through a second pyrotechnic pipe, the second smoke collecting box is communicated with the third smoke collecting box through a third pyrotechnic pipe, and thethird smoke collecting box is communicated with a smoke exhaust port; The combustion chamber is provided with a combustion device. The invention has the advantages that the special structural design increases the flow length of the hot smoke, increases the contact area between the hot smoke and the water, makes the steam generation speed faster, and improves the heating efficiency of the boiler atthe same time.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a multi-return gas boiler. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mainly used in daily life, and also have a sma...
