Abstract

The invention discloses a graded heating boiler which comprises a boiler body. At least two layers of heating coils are arranged in the boiler body. Combustion devices are arranged on the outer wall of the boiler body and at positions below the heating coils, and can jet flame to parts below the heating coils. Blower devices are arranged on the outer wall of the boiler body and at positions below the combustion devices. An exhaust duct is arranged on one surface, corresponding to the blower devices, of the boiler body. Exhaust inlets are formed in the exhaust duct and at positions corresponding to the blower devices. The grade heating boiler adopts a graded heating manner, a corresponding quantity of combustion devices are opened according to the temperature requirement, the heating coils are heated to reach the required temperature, besides, symmetrical air sucking and air exhausting structures are adopted, so that the temperature of the boiler is accurately controlled, the energy waste is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a hierarchical heating 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...
