Energy-saving boiler

Abstract

The invention discloses an energy-saving boiler, and relates to the technical field of energy-saving boilers. A water storage device is fixed in a boiler body of the energy-saving boiler, a water inlet end and a water outlet end are arranged at the top and the bottom of the rear side of the water storage device correspondingly, the part, located at the bottom of the water storage device, in the boiler body is a combustion heating area, and an overhaul door plate is installed at the position, located at the combustion heating area, of the front side of the boiler body; and a fuel adding opening and an oxygen inlet are formed in the portions, located at the left side and the right side of the combustion heating area, of the furnace body correspondingly, and an inwards-concave hemispherical part is arranged at the bottom of the water storage device. According to the energy-saving boiler, the heating effect of coal on the water storage device in the combustion heating area can be improved by arranging the inwards-concave hemispherical part at the bottom of the water storage device, smoke generated by coal combustion can be exhausted by arranging a smoke exhaust cylinder, and meanwhile, the smoke exhaust cylinder penetrates through the water storage device, so that high-temperature flue gas in the smoke exhaust cylinder can heat water in the water storage device, and the water heating efficiency of the boiler is improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving boilers, in particular to an energy-saving 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 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 small amount of application in industrial production. Boilers that generate steam are called steam boilers, often referred to simply as boilers, and are mostly used in thermal p...

Problems solved by technology

[0003] The existing vertical boilers that use coal as fuel have the disadvantage of slow heating speed in the process of heating water. Correspondingly, it will also increase the energy consumption of boiler heating water and increase the consumption cost of coal.
