1-ton gas boiler features:
The unit is equipped with overheat protection (the burner automatically stops working and emits an alarm when the water temperature inside the furnace exceeds the safe limit), secondary overheat protection (the secondary circuit is automatically disconnected when the boiler shell temperature exceeds 105℃), dry burn and low water protection (the boiler stops working and emits an alarm when the water level is below the minimum), and electrical leakage protection (the power supply is automatically disconnected when the control system detects electrical leakage or short circuit).
Boilers are designed with atmospheric pressure structure, operating in a pressure-free state, ensuring no safety hazards. They are insulated with high-grade centrifugal glass wool in multiple layers and encased in superior white color steel plates, which minimize heat loss and offer both aesthetic appeal and corrosion resistance.

4The flue pipe is fitted with flame-retardant turbulence plates, which slows down the exhaust gas speed, enhances heat exchange, and results in lower exhaust gas temperature from the smoke chamber, reducing heat loss and saving fuel.
Boiler heat loss
1. Heat loss caused by flue gas emissions from gas boilers is primarily due to the volume of flue gas and the emission temperature. During the exhaust process, when the boiler is not in a sealed state, air flow carries away some heat, resulting in heat loss. Flue gas emissions account for the largest proportion of heat loss, approximately 4.5%-8.2%.
2. Heat loss due to incomplete fuel combustion, primarily caused by two factors. One is the presence of combustible gas components in the flue gas within the boiler, which is related to the furnace temperature, air coefficient, and the mixing flow of fuel and air, thereby affecting the volatilization speed and content of the fuel. The other is the incomplete combustion of solid fuel, more influenced by the granular nature of the solid fuel. During combustion, if the temperature is not high and the airflow is poor, the flying ash can easily form sediments. Too much sediment accumulation prevents the remaining fuel particles from being completely combusted, leading to the formation of carbon black and causing heat loss in solid fuel gas boilers. Factors such as fuel properties, moisture content, temperature, power load, and the air propulsion force within the boiler can easily lead to fuel heat loss.
3. Heat Loss from Gas Boilers: The heat loss that occurs when the metal structures of the boiler unit, such as the furnace walls and flues, are exposed to the atmosphere and dissipate heat into the outside air is known as heat loss. This loss is directly related to the surface area of the boiler unit, its insulation, and thermal insulation conditions.
4. Heat loss due to boiler ash and slag sediment: During the combustion process of fuel in a gas-fired boiler, as the internal temperature of the boiler continuously rises, the heat loss caused by the expulsion to the outside of the boiler is referred to as the heat loss due to boiler ash and slag sediment.
Combustion Equipment
During the development of boilers, the type of fuel has a significant impact on the furnace and combustion equipment. Therefore, it is not only necessary to develop various furnace types to accommodate the burning characteristics of different fuels but also to enhance combustion efficiency to conserve energy. Moreover, technological improvements to the furnace and combustion equipment require minimizing pollutants (*oxides and nitrogen oxides) in the boiler's exhaust.
Mechanized Grate
Early potshell boilers used fixed grates, primarily burning high-quality coal and wood, with manual operations for coal addition and slag removal. The introduction of the straight tube boiler led to the adoption of mechanized grates, with chain grates gaining widespread use. The under-grate air supply evolved from a non-segmented "common storage air" to segmented supply. Initially, the combustion chamber was low and inefficient. Later, recognizing the role of the combustion chamber volume and structure in combustion, the chamber was made taller, and arches and secondary air were introduced, thereby improving combustion efficiency.
Room furnace
When the generator set's power exceeds 6 megawatts, the grate sizes of these layer combustion furnaces are too large and the structures are complex, making them difficult to arrange. Therefore, room combustion furnaces began to be used in the 1920s, which burn coal powder and oil. Coal is ground into coal powder by a coal mill and then injected into the furnace chamber for combustion using a burner. As a result, the capacity of the generator set is no longer limited by the combustion equipment. Since the early stages of World War II, almost all power station boilers have adopted room combustion furnaces.
Direct Current Burner
Early coal powder furnaces used an U-shaped flame. The coal powder gas stream emitted by the burner first descends in the furnace chamber and then turns to rise. Later, a swirl-type burner arranged on the front wall emerged, forming an L-shaped torch in the furnace chamber. As the boiler capacity increased, the number of swirl-type burners also grew, which could be arranged on both side walls or on the front and rear walls. Around 1930, a straight-flow burner arranged at the four corners of the furnace chamber and mostly in a circular combustion manner appeared.
Fuel boiler
Post-World War II, with oil prices low, many countries began widely using fuel oil boilers. These boilers were easily automated. After oil prices increased in the 1970s, many nations shifted back to coal resources. By then, power plant boilers also grew in capacity, demanding combustion equipment that not only burns completely and ignites stably but also operates reliably, performs well under low loads, and must reduce pollutants in the exhaust.
In coal-fired (especially lignite-fired) power plant boilers, the use of staged combustion or low-temperature combustion techniques, such as delaying the mixing of coal powder with air or injecting flue gas into the air to slow down combustion, or dispersing burners to control the furnace temperature, not only suppresses the formation of nitrogen oxides but also reduces slagging. Boiling combustion, a type of low-temperature combustion, is capable of burning solid fuels with very high combustible ash content and can also mix limestone in the boiling bed for desulfurization.
Gas boiler
Boilers were once a symbol of the industrial age, but as time has passed, these relics of the old industrial era are increasingly difficult to fully meet the needs of modern enterprises. So, how should boiler companies struggling with diseases find a solution? Gas boilers can help you out!
Generally, common issues with boilers include being costly and environmentally unfriendly, posing high safety risks, requiring dedicated management due to large space requirements, and being麻烦 to operate with the need for various safety permits. Using gas hot water heaters can address all these issues. Firstly, regarding cost and environmental impact, gas boilers utilize combustible gases with zero emissions. They also come with intelligent pressure control, eliminating risks of explosions or carbon monoxide poisoning. Being a high-tech product, gas boilers have a small footprint, are easy to operate without the need for a specialist, and start automatically with just a button press. Since they are not coal-fired, they also do not require any safety permits.
