"Fuel Gas Atmospheric Pressure Hot Water Boiler" Detailed Introduction
Categories.
The atmospheric hot water boilers are mainly categorized by their fuel types, including atmospheric gas-fired hot water boilers, atmospheric oil-fired hot water boilers, and atmospheric coal-fired hot water boilers, among others.
Application
Hot water boilers are primarily used for heating and bathing purposes. They circulate hot water from a storage tank using a hot water circulation pump, continuously heating the water in the tank to achieve bathing goals. Additionally, hot water boilers circulate hot water through heating pipes using the circulation pump, which, when passed through radiators (heating panels), fulfill people's heating needs. The combination of hot water boilers, hot water circulation pumps, and heat exchangers allows for both bathing and heating functions.
Item 2: Atmospheric Pressure Fuel-Gas Hot Water Boiler
Atmospheric pressure fuel (gas) hot water boilers, powered by diesel or natural gas, heat water through burners to provide heating and hot water for domestic use and bathing. These boilers are highly intelligent, quick to heat, low in noise, and dust-free, making them an economical and popular boiler type well-suited to China's national conditions. The boiler can independently meet heating needs as well as hot water supply. If a heat exchanger is added to the piping system, the boiler can simultaneously fulfill both heating and bathing requirements.
Control System
Equipped with a dedicated microcomputer controller for hot water boiler operation, featuring a large, full-Chinese LCD screen with a super-bright backlight, ensuring the boiler's running status is clearly visible day or night. Comprehensive display includes: circulation pump operation, burner operation, water temperature, water level high/low, current time, alarm records, and more. The boiler's running status is fully covered; easy to set up: after the boiler is turned on, operators can easily access standby mode (settings), enter running mode (start), or exit running mode (stop) through 6 buttons. They can freely set operating parameters while in standby mode; comprehensive functions: allows setting current time, alarm temperature, water temperature upper limit, water temperature lower limit, circulation pump start/stop temperature, and boiler on/off times (divided into 4 time periods). Typically, operators only need to press the "Start" button to turn on the boiler and the "Stop" button to turn it off, which is very simple.
2. Combustion System
Utilizing original imported burners, featuring fully automatic programmable control, automatic fan sweeping, electronic ignition, and automatic oil-gas combustion with proportional adjustment, the atomization effect is excellent, combustion is complete, energy-saving and environmentally friendly, with an extinguishing protection device ensuring combustion safety. Normally, the burner output adjusts the flame length automatically with the boiler temperature. When the boiler outlet temperature reaches the set value, the burner automatically stops combustion. When the temperature falls below the set value, the burner automatically starts working. In case of abnormal fuel or air intake, the fault light illuminates, and the programmed control stops fuel output immediately, causing the combustion unit to automatically shut down.
3. Furnace Design
Boilers are designed for atmospheric pressure operation, featuring an air vent at the top to eliminate the risk of explosion. The boiler body is designed through computer-optimized simulation, ensuring optimal dimensions and a harmonious, aesthetically pleasing shape. The CLHS vertical boiler utilizes an under-burner combustion method, with fuel burning under slight positive pressure inside the furnace. High-temperature flue gases undergo radiant heat exchange within the furnace, followed by convective heat exchange in the flue tubes, and finally排出 through the upper smoke box. Baffle plates are inserted into the flue tubes to slow down the exhaust speed of flue gases, enhance heat exchange, and ensure that the heat produced by fuel combustion is maximally transferred to the boiler water, significantly improving the boiler's thermal efficiency. The CWNS horizontal boiler employs a full-wet back three-pass structure, with a long flue gas flow path that reduces exhaust gas temperature. The full corrugated furnace design creates strong flame disturbance, significantly increasing the heat transfer coefficient and effectively preventing equipment lifespan reduction due to metal thermal expansion and contraction. Large-diameter flue tubes and large-pored bridge gaps allow for a thin scale buildup on the boiler in equal time, making cleaning easier.
4. Multiple Protection
Boilers feature multiple safety protections: electrical leakage protection automatically cuts off power; overheat protection stops the burner and sounds an alarm when the boiler water temperature exceeds the alarm temperature; secondary overheat protection automatically cuts off the secondary circuit and stops the boiler when the boiler shell temperature exceeds 105℃; dry burning protection constantly monitors water levels with high-quality water level electrodes, and the boiler stops operating if the water level reaches or falls below the critical low level due to other reasons, preventing the risk of dry burning.
5. Insulation Performance
Glass wool is used for overall thermal insulation, which is lightweight, provides excellent thermal insulation, and has minimal heat loss.
6. Overall Appearance
White color steel plate packaging, attractive and spacious, good sealing and corrosion resistance, mechanical and electrical integration, small space occupation, easy to use.
