Energy-saving hot water boiler

Abstract

The invention discloses an energy-saving hot water boiler, relating to the technical field of boilers. The energy-saving hot water boiler comprises a boiler body, a boiler hearth and a chimney, wherein a clapboard is arranged on the upper part inside the boiler body, the outer periphery of the clapboard is connected in the boiler body in a sealing way, the clapboard is provided with a central hole, the boiler body is internally and vertically provided with a first watertight shutter, a second watertight shutter and a third watertight shutter, which are all in hollow column shapes, an auxiliary fire pipeline is vertically arranged between the first watertight shutter and the second watertight shutter, a smoke pipe is vertically arranged between the second watertight shutter and the third watertight shutter, a smoke exhaust pipe is vertically arranged between the third watertight shutter and the side plate of the boiler body, the lower end of a smoke inlet pipe is communicate with the lower end of the smoke exhaust pipe, a first smoke and fire shield and a second smoke and fire shield are opened downwards and are arranged between the upper top plate of the boiler body and the clapboard, the first smoke and fire shield is arranged outside the second smoke and fire shield, a through hole is arranged on the clapboard between the first smoke and fire shield and the second smoke and fire shield, and a water outlet is arranged between the second watertight shutter and the boiler hearth. The boiler has the advantages of simple and reasonable structure, high heat utilization rate, energy saving and high efficiency and is easy for production and manufacture.

Description

technical field [0001] The invention relates to the technical field of a boiler, in particular to the technical field of a hot water boiler with an energy-saving effect. Background technique [0002] Boilers are generally composed of furnaces and drums, etc., and have been widely used in industry, agriculture and life. Boilers can be divided into hot water boilers that provide hot water and steam boilers that provide steam; the steam and hot water generated by the boilers provide people with production According to the needs of life, the bottom of the drum of the existing vertical hot water boiler is equipped with a furnace, and the central axis of the drum is equipped with a pyrotechnic channel. The pyrotechnic channel is linear, and the upper part is directly discharged into the atmosphere with the chimney after passing through the dust removal and desulfurization equipment, resulting in waste of heat energy. .
