"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-fired 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. They circulate hot water from the保温水箱 through a hot water circulation pump, repeatedly heating the water in the tank to achieve bathing purposes. The boiler also circulates hot water through the heating pipes using the circulation pump, which is then distributed via radiators (heating panels) to meet heating requirements. In conjunction with a heat exchanger, the hot water boiler and circulation pump can accomplish both bathing and heating functions.

Item 2: Atmospheric Pressure Fuel Gas Oil Water Boiler

Atmospheric pressure fuel (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 meet heating needs alone or hot water supply alone. 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, featuring a large full-Chinese LCD screen with super-bright backlight, making the boiler's operating status 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, covering all aspects of the boiler's operating status. Easy to set up: after the boiler is turned on, operators can freely switch to standby mode (settings), enter operation mode (start), or exit operation mode (stop) through 6 buttons. Parameters can be set freely while in standby mode. Full-featured: allows setting current time, alarm temperature, upper and lower water temperature limits, circulation pump start/stop temperatures, 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 programmed control, automatic fan sweeping, electronic ignition, automatic oil-gas combustion, and automatic proportioning of fuel and air (or gas), with excellent atomization and complete combustion. Energy-saving and environmentally friendly, equipped with an automatic shutdown protection device for safe combustion. Under normal conditions, the burner output adjusts the flame length automatically according to the boiler temperature. When the boiler outlet temperature reaches the set value, the burner automatically stops combustion. If the temperature falls below the set value, the burner automatically starts working. In case of abnormal fuel or air supply, the fault light illuminates, and the programmed control immediately stops fuel output, automatically shutting down the combustion unit.

3. Furnace design

Boilers are designed for atmospheric pressure operation, featuring an open 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 at a 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 exit through the top smoke box. Baffle plates are inserted inside the flue tubes to slow down the exhaust speed of flue gases, enhance heat exchange, and ensure that the heat generated by fuel combustion is maximized for heating 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 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 bridge gaps allow for a thin scale deposit on the boiler and facilitate cleaning.

4. Multi-protection

The boiler features multiple safety protections: leakage protection, which automatically cuts off power in case of a 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 outer shell temperature exceeds 105℃; dry burning protection, which monitors the water level in real-time with a precise water level electrode rod, stopping the boiler when the water level reaches or falls below the extremely low level to prevent dry burning hazards.

5. Insulation performance

Glass wool is used for all-around thermal insulation, featuring light weight, excellent thermal retention, and minimal heat loss.

6. Overall Appearance

White color coated panel packaging, aesthetically pleasing, good sealing and corrosion resistance, mechanical and electrical integration, compact space usage, easy to use.

Integrated low-NOx condensing boilers feature a large vapor phase space, equipped with an efficient vapor-water separator, reducing steam humidity to below 3%; they utilize advanced digital intelligent control technology for precise remote monitoring of the entire combustion process. Reliable imported electrical components ensure the equipment's safety and reliability during operation. Optional remote communication interfaces can be added to parallel control multiple boilers, allowing real-time printing of boiler operating parameters. The computer memory system can record boiler malfunctions and monitor boiler operation.

Comprehensive safety accessories for boilers, including water level control, pressure control, alarm devices, gas leak prevention, blowout protection, over-temperature and over-pressure protection, explosion-proof door protection, etc. Multiple safety interlock protections ensure the equipment is free of safety hazards. The boiler is equipped with internationally advanced imported burners, ensuring complete combustion and harmful components in the flue gas below national standards, making it an environmentally friendly product.
