"Fuel Gas Atmospheric Pressure Hot Water Boiler" Detailed Introduction
Categories.
Atmospheric pressure hot water boilers are mainly categorized by the type of fuel used, including atmospheric pressure gas hot water boilers, atmospheric pressure oil-fired hot water boilers, and atmospheric pressure coal-fired hot water boilers, etc.
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, repeatedly heating the water in the tank to achieve bathing goals. Additionally, hot water boilers circulate hot water through heating pipes using the same pump, which, when passed through radiators (heating panels), meet the requirements for heating. The combination of a hot water boiler, hot water circulation pump, and a heat exchanger allows for both bathing and heating functionalities.
Section 2: Atmospheric Pressure Oil-Gas Water Boilers
Atmospheric pressure oil (gas) hot water boilers, fueled 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 or supply hot water. 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 ultra-bright backlight, ensuring the boiler's operating 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 operating status is fully covered; settings are easy: after the boiler is turned on, operators can freely switch to standby mode (settings), enter operation mode (start), or exit operation mode (stop) via 6 buttons. They can freely set operating parameters while in standby mode; the functions are complete: parameters such as current time, alarm temperature, water temperature upper limit, water temperature lower limit, circulation pump start/stop temperature, and boiler on/off time (divided into 4 time periods) can be set arbitrarily. 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 programmed control, automatic fan sweeping, electronic automatic ignition, automatic oil-gas combustion, precise fuel-air (gas) ratio adjustment, excellent atomization, complete combustion, energy-saving and environmentally friendly, equipped with an automatic flame-out protection device for enhanced combustion safety. Under normal conditions, 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 operating. In case of abnormal fuel or air supply, a fault light illuminates, and the programmed device immediately stops fuel output, leading to the automatic shutdown of the burner.
3. Furnace design
Boilers are designed for atmospheric pressure operation, featuring an open vent at the top to eliminate explosion risks. The boiler body is computer-optimized for a sleek and aesthetically pleasing design, with dimensions fully optimized. The CLHS vertical boilers utilize a bottom-mounted burner combustion method, where fuel burns at a slight positive pressure within the furnace, with high-temperature flue gases undergoing radiant heat exchange inside the furnace and then convective heat exchange in the flue tubes before exiting through the top smoke box. Baffle plates are inserted into the flue tubes to slow down the flue gas flow, enhance heat exchange, and ensure that the heat produced by the fuel combustion maximizes the heating of the boiler water, significantly improving the boiler's thermal efficiency. The CWNS horizontal boilers employ a full-wet-back three-pass structure, with a long flue gas path that reduces exhaust gas temperature. The full-wavy furnace pot generates strong flame disturbance, significantly enhancing the heat transfer coefficient and effectively preventing equipment lifespan reduction due to metal expansion and contraction. Large-diameter flue tubes and large-bridge gaps allow for thin scale deposits over time and easy cleaning.
4. Multiple Protection
Boilers come with multiple safety protections: electrical leakage protection, which automatically cuts off power in case of leakage; overheat protection, which stops the burner and sounds an alarm when the boiler water temperature exceeds the alarm temperature; secondary overheat protection, which cuts off the secondary circuit and stops the boiler when the boiler shell temperature exceeds 105℃; dry burning protection, which monitors water levels in real-time with precision water level electrodes, stopping the boiler when the water level reaches or falls below the critically low level, preventing the risk of dry burning.
5. Insulation performance
Glass wool is used for overall thermal insulation, offering light weight, excellent thermal performance, and minimal heat loss.
6. Overall Appearance
White color board packaging, attractive and spacious, good sealing and rust resistance, mechanical and electrical integration, small space occupation, easy to use.
