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.
1) The entire plant may be purchased as a complete package, only needing securing to basic foundations, and connecting to water, electricity, fuel and steam systems before commissioning. This means that installation costs are minimised.
2) This package arrangement also means that it is simple to relocate a packaged shell boiler.
3) A shell boiler contains a substantial amount of water at saturation temperature, and hence has a substantial amount of stored energy which can be called upon to cope with short term, rapidly applied loads.
*This can also be a disadvantage in that when the energy in the stored water is used, it may take some time before the reserve is built up again.
4)The construction of a shell boiler is generally straight forward, which means that maintenance is simple.
5)Shell boilers often have one furnace tube and burner. This means that control systems are fairly simple.
Although shell boilers may be designed and built to operate up to 27 bar, the majority operat
The combustion method of the boiler equipment is also a factor that the majority of users will consider when selecting the boiler. Depending on the combustion method, the boiler structure and boiler room layout will be different.
The automatic boiler water level controller is mainly composed of hardware and software parts to complete the functions of the control system. The hardware part is mainly composed of the water level detection circuit, drive circuit, water level indication circuit, pressure automatic control simulation, manual control, etc. The software part is mainly composed of the programs written in assembly language.
The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
The dual-fuel boilers usually burn oil and gas fuel which can be natural gas fuel or artificial gas fuel such as natural gas or diesel. The field-assembled dual-fuel boilers also burn the heavy oil or light oil. This type of boiler can make enterprises select the fuel more flexibly and minimize the boiler operating and production costs for enterprises.
