Regular maintenance is essential to ensure safe and efficient operation of industrial thermal oil heaters. Here are some of the key maintenance tasks that should be performed:
1. Daily checks: The operator should perform daily checks of the heater, including checking the fuel level, the temperature of the thermal oil, and the pressure of the system.
2. Cleaning: The heater should be cleaned regularly to remove any buildup of soot, ash, or other debris that can reduce efficiency or cause damage...
An Interlock in the boiler’s control system is a programmed or hardwired condition that forces a device to be in a pre-determined or permissive state before the process can continue.
Depending on design pressure, fuel type, either liquid, gas or solid, all steam boiler require interlocks to sequence the operation and to prevent damage to the boiler. Examples of such devices are High or Low Boiler Drum Water Level, Low Boiler Feed Pump Pressure, High or Low Fuel pressure, High or Low Atomization pressure (oil fired), Proof of Ignition, Proof of Flame, FD and/or ID (solid fuel) Fan Motor Operation or combustion air pressure, Damper or Valve position and High Boiler Steam Pressure as well as O2 and furnace temperature.
The circulating pressure of a thermal oil boiler is generated by the driving of the circulating oil pump to the thermal oil circulation. Generally, the working pressure of the thermal oil pump is 4 ~ 8kg / cm2. Actually, the pressure of the thermal oil pump differs from different working conditions.
What are the factors that affect the maximum pressure of thermal oil heater?
1. Pressure of circulating hot oil pump
The pressure of liqu...
The burner of natural gas boiler refers to the burner for gas-fired boiler. Gas burners are divided into natural gas burners, urban gas burners, LPG burners and methane burners. The burner of natural gas boiler is just one kind of burner.
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
Combustion is a process which needs constant air supply for its survival, but as we move up the earth i.e. at higher altitudes, things aren’t the same as they used to be at sea level. Due to decreased air density at higher altitude, it will consume the same volume of air but will not consume the same mass of air.
This results in less fuel consumption & less steam generation rate. Due to the reduction of mass flow of gases through tubes of a steam boiler, convective heat transf...
To guarantee the successful and efficient shell boiler operation, the user must:
1)Know the conditions, environment, and demand characteristics of the plant, and accurately specify these conditions to the boiler manufacturer.
2)Provide a boiler house layout and installation that promotes good operation and maintenance.
3)Select the control systems that allow the boiler to operate safely and efficiently.
4)Select the control systems that will support the boiler in supplying dry steam to the plant at the required pressure(s) and flowrate(s).
5)Identify the fuel to be used and, if necessary, where and how the fuel reserve is to be safely stored.
Textile is one of the industries that cannot be separated from steam boilers. Whether it is dyeing or drying, boilers can speed up production smoothly. The oil-fired steam boiler is very suitable for textile mills. The oil-fired steam boilers produced by ZOZEN for textile mills mainly include SZS oil-fired steam boilers and WNS oil-fired steam boilers.
