Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
Heavy oil for industrial boilers, namely fuel oil, is mainly made from petroleum cracking residue and straight-run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, gums and asphaltenes. Among them, the viscosity of industrial boiler special oil is an important performance index of fuel oil, and it is also the main basis for dividing fuel oil grades.
The so-called tower boiler refers to a boiler with a furnace at the lower part and a convection flue at the upper part. The features of domestic tower and tanks include the following aspects.
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.
