Description

Technical Field

[0001] This utility model relates to the field of energy-saving heating boiler technology, and more specifically to an energy-saving gas-fired heating boiler. Background Technology

[0002] With increasing global awareness of environmental protection, traditional coal-fired boilers are gradually being replaced by gas-fired boilers. Gas-fired boilers use clean energy sources such as natural gas as fuel, and the exhaust gases produced after combustion contain significantly fewer harmful substances than those from traditional coal-fired boilers. This characteristic makes gas-fired boilers an important option for providing clean and efficient energy during the energy transition. The widespread application of gas-fired boilers helps reduce greenhouse gas emissions and other harmful emissions, playing a positive role in improving air quality and protecting the ecological environment.

[0003] However, existing gas boilers are not very energy-efficient. They often have low overall heating efficiency because the heat in the combustion chamber is not fully utilized. This means that more energy is wasted instead of being converted into usable heat to raise the indoor temperature or provide domestic hot water and other services.

[0004] Furthermore, when the gas enters the combustion chamber at a relatively high speed, incomplete combustion may occur due to uneven mixing with air or insufficient residence time. This not only further reduces thermal efficiency but may also produce harmful gases such as carbon monoxide, causing environmental pollution and posing a potential threat to human health.

[0005] Therefore, in order to solve the above problems, this application provides an energy-saving gas-fired boiler for heating. Utility Model Content

[0008] Preferably, the main component includes a heating furnace, a limiting sleeve, and a combustion chamber, wherein the heating furnace is disposed on the combustion chamber, the combustion chamber is engaged with the heating furnace, and the limiting sleeve is fixedly installed on the combustion chamber.

[0009] Preferably, the heating valve includes a valve plug, a valve body, an external sleeve, a rotary motor, a threaded screw, a sliding disc, a compression spring, and a retaining disc.

At this time, the rotary motor drive shaft drives the threaded screw to rotate, and under the meshing action with the valve body, it drives the sliding disc and valve plug to move downwards as a whole, allowing water vapor in the heating furnace to be discharged into the external sleeve through the valve body.

[0010] Preferably, the preheating assembly includes a first water inlet pipe, a water valve, a water transport pipe, a heat-conducting plate, a first connecting sleeve, a first power motor, a first rotating blade, and a second water inlet pipe.

The first power motor is fixedly engaged with the first connecting sleeve, and the first power motor drive shaft is fixedly engaged with the first rotating blade. When the water valve is turned, water enters the water transport pipe through the first water inlet pipe. Part of the water directly enters the heating furnace cavity, and the other part enters the lower part of the water transport pipe. Simultaneously, the first power motor drive shaft drives the first rotating blade, which, under the rotation of the first rotating blade, carries the water from the lower part of the water transport pipe out and into the heating furnace through the second water inlet pipe.

[0011] Preferably, the gas assembly includes a gas pipe, a gas valve, a gas ring, a gas port, a second connecting sleeve, a second power motor, a second rotating blade, an air inlet ring, and an air outlet.

[0012] Preferably, the support assembly includes a support base and support columns, the support base being fixedly installed at the bottom of the combustion chamber, and the support columns being fixedly installed at the four corners of the support base.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] When the boiler is working, turning the water valve allows water to enter the water supply pipe through the first inlet pipe. Part of the water enters the inner cavity of the heating furnace directly, while the other part enters the lower part of the water supply pipe. The residual heat inside the combustion chamber is conducted to the water supply pipe through heat-conducting fins, preheating the water inside the water supply pipe. At the same time, the first power motor drives the first rotating blade to carry the preheated water into the heating furnace through the second inlet pipe, effectively improving the heat utilization rate. When the gas valve is turned to allow the gas to burn through the gas port, the second power motor drives the second rotating blade to discharge air through the gas outlet, ensuring complete combustion and improving the gas combustion efficiency.
