Atmospheric steam domestic boiler

Abstract

The invention relates to an atmospheric steam domestic boiler which comprises a boiler furnace, a boiler shell, a combustor, a steam chamber and a chimney, wherein boiler water is filled between the boiler furnace and the boiler shell. The atmospheric steam domestic boiler is characterized in that at least one water tank communicated with the boiler water is arranged outside the boiler, and the at least one water tank is communicated with the air. Due to the fact that the water tanks are arranged additionally on the rear portion of the boiler to prevent the boiler from being closed and bearing pressure, and favorable guarantee is provided for absolutely safe running of the steam boiler. Besides, a reciprocating steam superheater pipe is additionally arranged in a top smoke discharging box of the boiler, and therefore smoke discharging temperature can be effectively reduced, steam temperature is increased, steam is dried, and an ideal steam utilization effect is achieved. According to the atmospheric steam domestic boiler, on the premise that the atmospheric steam domestic boiler is not closed or pressurized, the steam temperature can reach to an ideal operating temperature, the produced steam can be used for a plurality of household equipment, and therefore the multiple function purpose is achieved, energy is saved, and absolute security is realized.

Description

technical field [0001] The invention relates to an energy-saving combustion equipment, in particular to an atmospheric steam domestic boiler, which belongs to the technical field of steam boiler atmospheric equipment manufacturing. Background technique [0002] For many years, pressure steam boilers have been widely used in steam boilers used in various areas of our country and in schools, hotels, hospitals, factories, troops and many other units. Because the overall structure of the pressure steam boiler is sealed, only a safety valve is installed on the top of the boiler. Due to the failure of the safety valve, the boiler explosion is easy to occur, so the danger is particularly high, and there are potential safety hazards at any time during use. Although the state stipulates that during the use of pressure steam boilers, safety valves must be inspected by the local regulatory authority every year before they can be installed and used. However, some units and individuals i...

Problems solved by technology

Because the overall structure of the pressure steam boiler is sealed, only a safety valve is installed on the top of the boiler. Due to the failure of the safety valve, the boiler explosion is easy to occur, so the danger is particularly high, and there are potential safety hazards at any time during use.

Although the state stipulates that during the use of pressure steam boilers, safety valves must be inspected by the local regulatory authority every year before they can be installed and used. However, some units and individuals install and use them privately in order to save costs, and even conceal the use of scrapped pressure steam boilers. Or accidents of boiler explosion due to improper human operation occur from time to time, which may easily cause casualties and property losses

[0003] Due to the simple internal design of the pressure steam boiler, the convection heating area in the furnace is small, the internal design space is large, and the exhaust gas temperature is high, so the thermal efficiency is low, the fuel consumption is large, and it is a waste of energy.

[0004] In addition, the cost of using pressure steam boilers is high, and the responsibility of the user is great. The supervision department needs to spend a lot of effort on supervision, which results in high supervision costs for the supervision department.
