China 2400kw Industrial Chain Grate Coal-Fired Hot Oil Boiler China

1. Who am I ?
I am a coal-fired horizontal thermal oil boiler (or hot oil boiler, thermal fluid boiler).
I am produced as the following steps:
2. What uniqure features do I have ?
2.1 High heat efficiency, unique structure, the heat efficiency can be more than 78%.
2.2 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.
2.3 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.
2.4 The unique design of furnace arch with our own patent can make the coal burn out fully to enhance the heat efficiency.
2.5 The convection area is equipped with an all-direction soot blower. This will reduce the difficulty of cleaning ash and prolong the service time.
2.6 High safety. When abnormal conditions happen, safety interlock system starts up tp protect the boiler system.
2.7 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.
2.8 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 enviromental protection.
3. How do I work for you?
4. What are my control and safety systems?
4.1 The instruments and valves are equipped at key places in the whole heating system to guarantee the integrity, safety and reliability of the control system.
4.2 Functions achievement (Basic requirements)
4.2.1 Steady and high temperature is supplied to meet the requirements of load.
4.2.2 Automatic load regulation is achieved.
4.2.3 Safety interlock and feedback protection are achieved in the abnormal conditons.
4.2.4 Early warning, alarm, fault display and locking are achieved.
4.2.5 Continuous and steady working status is achieved.
4.2.6 Manual and automatic working can be achieved as customer's requirement.
4.3 Main controls
4.3.1 Control the oil pressure at key spots
4.3.2 Control the oil temperature at key spots
4.3.3 Control the smoke temperature at key spots
4.4 List of system main monitoring points (basic requirements)
