-
Because the 3-pass fire tube steam boiler system has a more compact structure, it occupies a smaller footprint than other furnace types. Also because of the dense arrangement of fire tubes, the boiler heats up faster. Given the production characteristics of the food industry, this boiler will be more suitable.
-
It is equipped with world-class brand burners such as Riello and UNIGAS. Fuel combustion is more in line with your factory production. Use a smaller flame to maintain the boiler temperature when the need of your food factory for steam is low. The fuel loss caused by purging the furnace chamber when starting the boiler system is avoided.
-
A customized boiler control system makes fire tube steam boiler control more arbitrary. We will configure the electronic control system for you according to your local furnace workers. However, with the development of technology, the operation of the boiler system is becoming more and more intelligent.
-
The higher the quality of the water supply, the less prone to problems and the longer the service life of the boiler. Therefore, equipped with an international brand of water treatment such as Fleck, Runxin, can make your boiler system more stable. We can recommend to you according to your water usage.
-
The boiler body uses a corrugated furnace bladder, threaded flue tubes and other boiler structures that can quickly exchange heat. At the same time, aluminum silicate fiber is used as an insulation material. The boiler can quickly heat up without causing a large amount of heat loss. When there is no economizer, the exhaust gas temperature is only 160~170℃.
The following are the different parameters corresponding to different boiler capacities of fire tube steam boilers in the food industry. If you are not sure about the boiler capacity you need, you can contact us. We will provide you with the corresponding technical support.
