Description

Technical Field

[0001] This utility model relates to a thermal energy component, specifically to a tube-side water-cooled combustion tube bundle. Background Technology

[0002] Hot water boilers, a crucial component in thermal energy systems, are essential for heating and hot water supply. They heat water to the required temperature using natural gas or electricity to meet the hot water needs of homes, businesses, and industrial sites. With a wide range of applications, they can be installed in basements, equipment rooms, and other locations. Hot water boilers are highly effective, providing a rapid and stable supply of large quantities of hot water, ensuring users always have ample hot water available. Their advantages are multifaceted: high energy efficiency, effective energy cost savings, relatively stable operation, and easy maintenance. They can reach the set water temperature quickly and operate continuously and stably, meeting hot water demands at different times of day. They provide reliable support for people's lives and production activities, making them an indispensable key component in modern heating systems.

[0003] In the prior art, 201220509462.2 describes a boiler convection tube bundle with a multi-pass mixed flushing structure. This invention addresses the problem of excessive ash accumulation and poor heat exchange in current boiler convection tube bundles that use a single flushing structure, either horizontally or vertically. The upper furnace drum is fixed to the upper ends of the first and second convection tube bundles, and the lower furnace drum is fixed to the lower ends of both. A furnace wall is provided on the outer sides of the first and second convection tube bundles. The upper furnace drum is positioned on the upper part of the furnace wall. One end of a first baffle plate is fixed to the lower part of the furnace wall, and the other end of the first baffle plate is inclined downwards relative to the horizontal plane between the first and second convection tube bundles. The baffle wall is vertically positioned with its lower end fixed to the lower furnace drum, and one end of a second baffle plate is fixed to the upper end of the baffle wall. This invention is used as the main heating surface of a water-tube boiler.

[0004] Existing boiler tube bundles cannot effectively allow gas mixing and combustion to proceed directly, resulting in each space being far from the finned tubes. Utility Model Content

[0006] This utility model is achieved using the following technical solution: a tube-side water-cooled combustion tube bundle, comprising a thermal support, finned tubes, square tubes, and combustion components. The thermal support has an assembly space, and the assembly space contains a mounting plate with an assembly gap. A heat exchange component, consisting of finned tubes and square tubes, is assembled within the assembly gap. The square tubes are positioned between two sets of finned tubes. The mounting plate divides the assembly space into a mixing space and a combustion space. The mixing space is located on one side of the finned tubes, and the combustion space is on the other side. The mixing space is a mixed gas space, which is a mixed gas equalization chamber. The combustion space contains a combustion component, which is an ignition component.

[0007] The ignition component is an ignition needle, and a flame monitoring device for detecting the flame is provided on one side of the ignition needle. A flame observation hole for observing the flame operation is provided on one side of the flame monitoring device.

[0011] The square assembly connecting plate is a square connecting flange, the combustion space is a combustion chamber, and the mixed gas equalization chamber is provided with a mixed gas transmission port.

[0012] Compared to existing technologies, the assembly space on the thermal energy support of this utility model provides a stable and efficient installation position for the heat exchange components through the installation of perforated plates and assembly gaps, which helps to improve the overall heat exchange efficiency. The mixing space, as a pressure equalization chamber for mixed gases, enables the mixed gases to be evenly distributed, ensuring the stability and completeness of combustion and improving energy utilization. The combustion space is equipped with an ignition needle, a flame monitoring device, and a flame observation hole, which not only facilitates ignition operation but also allows for real-time monitoring of the flame status, ensuring the safety and reliability of the combustion process and facilitating the timely detection and handling of abnormal situations. The upper and lower headers, together with the inlet and outlet water pipes and corresponding flanges, ensure smooth water circulation and facilitate connection with external systems, enhancing the adaptability and operability of the entire device.
