Three-pass steam boilers are so-called because the combustion gases that are produced inside them in the burner go round a circuit that has three parts before leaving it:
Whether it's an industrial hot water boiler or an industrial steam boiler, they all depend on fuel to run. The process of heating is initiated as the burner heats or eventually evaporates the water inside of it. It's actually transported via intricate pipe systems.
Steam boilers transport through the pressure created by the process, while hot water boilers use pumps to move heat throughout the system. Eventually the condensed steam or cooled water returns back through the pipes to the boiler system, so the heating process can be initiated again.
As the boiler creates heat energy, a byproduct of the process — flue gases — are exited through a chimney system. Because of this, regulating the industrial boiler emissions is a very serious issue.
Oil Fired Boilers generally require Day Oil Tank to store oil and this oil is transported to a burner through oil piping and oil pump. On the other hand, High-Efficiency Gas Fired Boilers are exactly same as Oil Fired Boilers in construction and the only difference is the transportation of gas to burner requires gas train which comprises of the gas regulator that regulates pressure, the gas strainer to remover dirt from gas while no such valves are required in oil fired boilers.
The efficiency of a coal-fired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, i.e. mainly carbon loss and dry gas loss.
For an industrial boiler with reasonable structural design, its thermal efficiency is relatively high, and its exhaust gas discharge temperature is relatively low, so we must carefully consider the boiler property report form when purchasing the boiler.
According to the differences in fuel and structure, industrial thermal oil heaters are mainly divided into the oil/gas-fired thermal oil heater and coal/biomass-fired thermal oil heater. The basic configurations of the thermal oil boiler system generally are as follows.
