Technical Field

[0001] The utility model belongs to the technical field of boiler heating, and relates to a modular condensing gas-electricity complementary inspection-free boiler system. Background Art

[0002] Energy-saving and environmental protection technologies are important means of addressing resource shortages and environmental pollution. They can reduce energy consumption and pollutant emissions, alleviating these issues. Secondly, by improving energy efficiency and reducing pollutant emissions, enterprises can reduce production and operating costs, thereby enhancing their competitiveness. Finally, the promotion and application of energy-saving and environmental protection technologies can promote technological innovation and industrial upgrading, and promote sustainable economic and social development. Accelerating the development and efficient use of clean energy at the end-user level is a key path to promoting coordinated and stable development and building a clean, low-carbon, safe, and efficient modern energy system. In particular, ensuring the energy needs of heating users and small industrial park users, and developing high-efficiency condensing boiler heating technology that uses natural gas as a complementary energy source, coupled with electricity, is of great significance, such as inspection-free boilers.

[0003] Inspection-exempt boilers are those with design parameters that allow a water volume (the total geometric volume of the steam-water system inlet and outlet) of less than 30L at the designed normal water level. These boilers are widely used in industrial, commercial, and civil applications such as steam supply, heating, and drying. In industrial production, these boilers can be used for steam supply and heating in the textile, printing and dyeing, and chemical industries; in the commercial sector, they can be used for hot water supply and heating in hotels, hospitals, and schools; and in the civil sector, they can be used for home heating and hot water supply.

In addition, once a heating component fails, the entire device will completely stop working, and there will be a heating gap during maintenance. Utility Model Content

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The utility model discloses a modular condensing gas-electric complementary inspection-free boiler system, comprising a boiler body and a water inlet pipe. Several heating surfaces are connected in series from top to bottom in the boiler body, the water inlet pipe is connected to the topmost heating surface, and the bottommost heating surface is connected to a gas-liquid separator.

[0017] Furthermore, a tail flue is provided on the boiler body, a flue gas damper valve is provided in the tail flue, a flue bypass is provided on the tail flue, an automatic bypass regulating valve is provided on the flue bypass, and the flue gas damper valve is located between the two connecting ports of the flue bypass and the tail flue.

[0018] Furthermore, the tail flue is located on the top of the boiler body, and the tail flue is connected to the chimney.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The boiler body of the present invention is a heating space where the burner heats each heating surface, and the water inlet pipe is used to input water to be heated to each heating surface. The electric heating component is used to realize electric heating of several heating surfaces. The burner is used to realize gas heating of several heating surfaces. Several heating surfaces are connected in series from top to bottom in the boiler body, and multiple heating surfaces are gradient heated to realize step-by-step heat transfer of the heat exchange surface, ensuring the stable operation of the entire system and preventing local high temperature from causing pipe burst.

[0024] 5. In the present invention, when the burner is turned off and only the electric heating assembly is used for heating, the furnace is in a closed state, which causes the temperature of the residual air inside the boiler body to rise, thereby causing the pressure inside the boiler body to rise. At this time, closing the flue gas damper valve and using the bypass automatic regulating valve for air pressure regulation is beneficial to reducing heat flow loss and ensuring the safe operation of the boiler body.
