Characteristics of oil (gas) indirect heating hot water boiler

1. The Quanxin indirect heating hot water boiler adopts a horizontal three pass wet back structure with a symmetrical center arrangement, which can improve the stress distribution of the plate and tube. The wet back structure combustion chamber and smoke box tube are completely immersed in water, with good cooling conditions. The design of a large combustion chamber is conducive to the spread of combustion flames and sufficient combustion.

2. The lower part of the main body, like a regular hot water boiler, consists of a combustion chamber and heat transfer tubes; The upper part is equipped with a heat exchanger, and the upper part of the furnace is equipped with an expansion water tank with automatic water level control.

3. The boiler operates safely and reliably under normal pressure as a whole; The heat medium water in the furnace does not enter or exit during operation, and transfers heat to the heat exchanger inside the boiler. The heat medium water is completely removed from oxygen and softened by heating, without corrosion or scale, making its service life about twice as long as ordinary boilers, up to 20 years.

4. Built in specially treated stainless steel or copper heat exchanger, with good heat transfer effect and fast heating.

5. The unit has a compact structure, easy transportation and installation, saves land occupation, eliminates the design and construction of heat exchange stations, and saves engineering costs.

6. By applying advanced digital control technology, the combustion process can be remotely and accurately monitored. The strong current part of the control cabinet adopts domestic and foreign famous electrical appliances, with reliable quality; The controller adopts LCD or touch screen controller, with high degree of automation, easy control, automatic control of combustion, water level, temperature, leak detection alarm, overpressure, overtemperature, water shortage protection and other interlocking guarantee functions.

7. Install a condensing heat exchanger at the smoke outlet, and use spiral fins to enhance the absorption of sensible and latent heat in the flue gas, reducing the exhaust temperature and improving the efficiency of the boiler (reaching over 95%).
