A steam generator is a mechanical equipment that uses the heat energy of fuel or other energy resources to heat water into hot water or steam. It belongs to small equipment and is a kind of steam boiler. According to Boiler Safety Technical Inspection Regulations, a boiler whose water volume exceeds 30 litres belongs to pressure container, national special equipment. There is no need of water storage in the internal structure of modular steam generator concurrent pipeline and the water volume is...
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
Based on the different methods involved in ash deposit over the heating surface, two types of ash deposition are observed, i.e. slagging and the fouling. Boiler slagging and fouling are two main factors that adversely affect the efficiency of boilers.
The construction and working principle of the boiler economizer is simple. At the bottom part, it has a horizontal inlet pipe through which we feed water with normal temperature to the economizer. There is another horizontal pipe fitted at the top of the economizer.
As their name implies, hot water boilers operate by being completely filled with hot water. On the other hand, steam boilers are usually only filled approximately 3/4th of the way full, while the top quarter is reserved for steam.
Gas consumption per hour of natural gas boiler = boiler thermal efficiency / natural gas calorific value / boiler efficiency. The higher the efficiency of boiler use, the less gas consumption, which has inverse relationship between the two. Boiler efficiency has become a key point in assessing boiler quality.
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.
