This is a coal-fired horizontal thermal oil boiler (or hot oil boiler). Simply, I consist of radiant section, convection section, chain grate furnace, coal feeder., insulation lay, steel coat, instrument valves and so on.

1. What uniqure features do I have ?

1.1 High heat efficiency, unique structure, the heat efficiency can be more than 78%.

1.2 Furnace radiation area adopts double square shaped coiler and on the top of boiler, we design the ceiling pipes, so that the heat load can be reduced on the surface of pipes and the thermal oil can work more safely.

1.3 In the end of boiler, we design a heating area with staggered arrangement. That will enhance the heat transfer coefficient and decrease the ash deposit in the boiler.

1.4 The unique design of furnace arch with our own patent can make the coal burn out fully to enhance the heat efficiency.

1.5 The convection area is equipped with an all-direction soot blower. This will reduce the difficulty of cleaning ash and prolong the service time.

1.6 High safety. When abnormal conditions happen, safety interlock system starts up tp protect the boiler system.

1.7 Accurate temperature control. The oil temperature difference in the outlet can be control with ±3 ºC. If the boilers are equipped with frequency conversion technology, we an control it within ±1 ºC.

1.8 The boiler can be equipped with a waste heat boiler in the rear, if users need hot water or steam from the heating system. That makes full use of the exhausted smoke to achieve energy-saving and environmental protection.

2. Our market in the world

Nowadays, we have exported our boilers to the following countries: India, Indonesia, Pakistan, Malaysia, Thailand, Laos, Vietnam, Bengal, Philippines, Taiwan China, Papua New Guine, France, Finland, Turkey, Serbia, Lithuania, Bulgaria, Russia, Mongolia, Venezuela, Chile, Colombia, Mauritius, South Africa, Ethiopia, Algeria, Nigeria, Tanzania, Oman, UAE, etc.
