Product Description

Fangkuai water tube hot water boiler series adopts a double drum longitudinal "D" type layout structure. A combustion chamber and heating surface are set outside the drum. Water, steam or steam-water mixture flows inside the tube, and flame and flue gas burn and flow outside the tube. , with extremely fast steam flow rate and excellent water circulation system, the boiler heat absorption rate and thermal efficiency are greatly improved.

Condenser and energy saving device

This condenser and energy-saving device utilizes the heat exchange principle between water and flue gas, and has the characteristics of fast heat transfer, energy saving, and durability. They cool the flue gases and increase the temperature of the boiler feed water.

Main auxiliary fans and FGR

The air-energy water heater adopts main and auxiliary fan matching technology and uses high-temperature condensed water to exchange heat with the inlet air. The auxiliary fan premixes some of the flue gases and coordinates the air supply from the inlet heater and the main fan. Unifiedly adjust the temperature of each node to stabilize combustion and control emissions.

Low nitrogen and environmentally friendly

Use well-known brand burners and reasonable furnace structure to ensure sufficient combustion. The exhaust gas composition complies with the national first-level regional environmental protection indicators, and the noise is lower than the national standard.

Energy efficient

The boiler flue gas and working fluid adopt a counter-current arrangement, with high average temperature and pressure and good heat transfer. Reasonably select the furnace volume to ensure full combustion of fuel. The insulation materials are aluminum silicate felt and ultra-fine glass wool, with a total thickness of about 200mm. There is an air sandwich between the two layers of insulation. This kind of insulation minimizes the heat loss of the boiler, greatly improves thermal efficiency, saves fuel, and reduces operating costs.

Product Advantages

One machine for multiple purposes

One machine for multiple purposes

The boiler has three operating modes: single, series and parallel. The number of boilers and operating status can be flexibly selected according to actual needs.

Simple and direct operation

Simple and direct operation

The boiler is equipped with modules such as high-color touch screen, dynamic graphic display, multi-level menus and permissions, and automatic fault saving records, which is very user-friendly.

Minimalist installation

Minimalist installation

The boiler is designed as a whole and debugged in the factory. The user only needs to install water and electricity on site and it can be used normally.

Ultra-low nitrogen emissions

Ultra-low nitrogen emissions

The boiler is diffusion combustion, which can adapt to the technical needs of large tonnage. The nitrogen oxide emission is less than 30mg, which meets the atmospheric emission standards.

Strong environmental adaptability

Strong environmental adaptability

The boiler is a high-temperature resistant type and can be used in areas with difficult environments such as high temperatures and high altitudes.

Safe And Reliable
