Full Premixed Combustion Gas Fired Hot Water Boiler Modular Design Variable Frequency Fan

Full Premixed Combustion Gas Fired Boiler Modular Design Variable Frequency Fan

Overview:

Environmental protection and cleanliness are the significant features of gas boilers. Compared with coal-fired boilers, gas boilers produce almost no dust and sulfide during the combustion process, and low nitrogen oxide emissions reduce the impact on air quality, contributing to the protection of blue sky and white clouds. At the same time, its rapid heating ability can meet users' needs for hot water and heating in a short time, saving waiting time. Combined with intelligent control and simple operation, users can easily set the operating mode and temperature through the control panel or mobile phone APP, and enjoy an intelligent heating experience.

Product  Introduction:

The boiler adopts the medium-pressure medium-temperature steam parameter design, and the overall layout is a single-cylinder horizontal chamber combustion structure, integrating the dual functions of industrial waste gas coordinated treatment and steam production. In the circulation system, in addition to the natural circulation main loop, an emergency forced circulation backup pipeline is configured to enhance system reliability. The front part of the furnace adopts a modular membrane water-cooled wall suspension system, which forms a three-level gradient heat exchange system (superheater-evaporator-condensing economizer) with the rear heat exchange unit, and the tail heating surface adopts a corrosion-resistant alloy support frame.

The combustion system adopts a dual-fuel adaptive low-nitrogen burner, combined with the graded wind distribution cyclone technology to achieve efficient incineration of exhaust gas. The pressure-bearing parts adopt a full suspension and elastic support composite structure, in which the boiler drum is fixed to the top of the steel structure by a hydraulic self-balancing hanger. The steel structure system uses an anti-seismic node design and integrates an intelligent detection walkway system. Especially in the waste heat recovery section, the innovative use of spiral finned tube heat exchange components improves thermal efficiency by 12% compared with traditional designs.

Compared with conventional boilers, this equipment integrates a flue gas recirculation system and is equipped with a multi-stage SCR reaction zone. When the steam parameters are maintained at 4.0MPa (steam pressure)/420℃ (steam temperature), the nitrogen oxide emission concentration can be controlled below 50mg/Nm³, achieving deep coupling between industrial production and environmental protection. The control system is specially equipped with a waste heat fluctuation adaptive module to ensure that saturated steam can be stably produced when the exhaust gas calorific value fluctuates by ±30%.

Advantages:

(1) Integrated with industrial waste gas treatment + steam production dual functions to meet strict environmental protection standards.

(2) The three-level gradient heat exchange system (superheater-evaporator-condensing economizer) and the spiral finned tube waste heat recovery component work together to form an efficient thermal system.

(3) The waste heat fluctuation adaptive module can cope with the fluctuating exhaust gas calorific value of ±30%, and cooperate with the dual-fuel burner + graded swirl air distribution to ensure continuous and stable steam output.

(4) The dual-circuit design of natural circulation + emergency forced circulation, combined with the fully suspended earthquake-resistant steel structure + corrosion-resistant alloy support frame, doubles the impact resistance and durability.

(5) The modular membrane water-cooled wall simplifies installation and maintenance, and the hydraulic self-balancing hanger + intelligent detection walkway system realizes real-time monitoring and rapid maintenance of pressure-bearing components.
