Environment-friendly and energy-saving boiler capable of using electricity and fuel gas

Abstract

The invention provides an environment-friendly and energy-saving boiler capable of using electricity and fuel gas, and belongs to the technical field of boilers. The environment-friendly and energy-saving boiler capable of using the electricity and the fuel gas comprises an electric steam generator, a fuel gas steam generator, a water inlet pipe, a water outlet pipe, a solenoid valve 5, a cabinetbody and a controller; the electric steam generator comprises a heating bin, a heating resistance, an electric steam main water tank, an electric steam auxiliary water tank, an electric steam liquid level meter, an electric steam bag and an electric steam water-returning pipe; the fuel gas steam generator comprises a fuel gas burning device, a fuel gas generating main water tank, a fuel gas generating auxiliary water tank, a fuel gas generating liquid level meter, a fuel gas generating heating pipe, a fuel gas generating steam bag, a fuel gas generating water-returning pipe and a fan. According to the environment-friendly and energy-saving boiler capable of using the electricity and the fuel gas, the arranged electric steam generator and the fuel gas steam generator are used for generatingsteam by using different energy sources, whether water feeding and steam discharging are conducted on the electric steam generator and the fuel gas steam generator or not are controlled through the arranged controller by controlling of the solenoid valve, different energy sources can be freely selected to supply steam, demands of more places can be met, and a wider range of using crowd is covered.

Description

technical field [0001] The invention belongs to the technical field of boilers, and in particular relates to an environmentally friendly and energy-saving furnace with both electricity and gas. Background technique [0002] Nowadays, many steam boilers sold in the market use relatively single energy, and respond slowly to changing energy prices and the market. Energy prices in different regions are also different, resulting in a relatively small sales range for boilers using a single energy source. At the same time, The steam boiler using a single energy source will affect the normal operation of the enterprise when the energy supply is temporarily unavailable. Contents of the invention [0003] In order to provide a steam boiler that can use a variety of energy sources, it can use both combustible gas to generate steam and electricity to generate steam, so as to avoid the trouble caused by the suspension of supply of a single energy source when a single energy source is u...
