Gas boiler classification

Gas boilers can be categorized by fuel type into natural gas boilers, city gas boilers, coke oven gas boilers, liquefied petroleum gas boilers, and biogas boilers, etc.; by function into KS-Q gas water boilers, CLHS/CWNS gas hot water boilers (including gas heating boilers and gas bathing boilers), LHS/WNS gas steam boilers, etc.; by construction into vertical gas boilers and horizontal gas boilers; and by flue gas flow into single-loop gas boilers and triple-loop gas boilers.

Features of Gas Boilers

1. Large font display of water temperature for easy monitoring of boiler and system operation. Water temperature can be set freely from 10℃ to 90℃, with the boiler automatically heating the system or providing hot water for domestic and bathing use.

2. The control system regulates the start and stop of the circulating pump based on the water temperature in the furnace. The hot water circulating pump activates when the water temperature reaches the set upper limit, and shuts off when it falls below the set lower limit.

3. The horizontal gas-fired hot water boiler features a three-pass full-wet back structure, utilizing a large furnace and thick flue tubes to enhance the radiation heat absorption in the furnace, effectively achieving energy saving and consumption reduction. The use of threaded flue tubes and corrugated furnace tubes significantly strengthens the heat transfer efficiency, greatly reducing fuel consumption.

4. The entire unit is equipped with overheat protection (the burner automatically stops working and emits an alarm when the water temperature inside the furnace exceeds a high level), secondary overheat protection (the secondary circuit is automatically disconnected when the boiler shell temperature exceeds 105℃), dry burn protection (the boiler stops working and emits an alarm when the water level is below the extremely low level), and electric leakage protection (the power supply is automatically disconnected when the control system detects electrical leakage or a short circuit).

5. Boilers are designed with atmospheric pressure structure, ensuring the boiler is in a non-pressurized state, with no safety hazards. They feature advanced multi-layered centrifugal glass wool insulation and high-quality white color steel plates for exterior packaging, resulting in minimal heat loss and aesthetic resistance to rust.

Huzhou Boiler FactoryThe YY(Q)W type gas heat-conducting oil boiler produced by our company is a new type of special boiler with low pressure and high-temperature operating characteristics. Its heating temperature can reach up to 340℃ in the liquid phase or 400℃ in the vapor phase. It can serve as a high-temperature heat source for temperatures below 350℃, widely used in various industries that require high-temperature heating or drying. It features high temperature, low pressure, precise temperature control, and high thermal energy utilization. Optional steam generators can produce saturated steam below 1.3MPa for user use. Organic heat carriers can be employed for heating in various production scenarios where uniform and stable heating is required and direct flame heating is not permitted, with heating temperatures ranging between 150℃ and 380℃.。The gas-fired organic heat carrier boiler typically uses oil or gas as fuel, with thermal oil as the medium. It employs a thermal oil circulating pump to force the medium into a liquid-phase circulation, transferring heat to the heat-using equipment before returning to the boiler for reheating. It boasts high working temperatures at low pressure and allows for high-precision control of the medium's operation. The system has a high thermal utilization rate, easy operation and maintenance, and is an ideal, safe, efficient, and energy-saving heating equipment of choice.。
