Manually close the fuel supply valve, stop the combustion, purge after the program enters, until the end of the purge, stop the program such as burning heavy oil, and enter the line sweeping stage before stopping the combustion, and purge with steam or light oil pipe; Generally, steam purging is used when stopping for a long time.

In the process of the development of national economy, the importance of boilers is self-evident. The so-called boiler is a device that uses the heat energy released by fuel incineration to heat water or other media, so as to obtain steam, hot water or other media with specific parameters (temperature and pressure).

Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.

When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure equipment, in accordance with local regulations.

It is generally agreed that where possible on steam boilers, the principal feedwater treatment should be external to the boiler.

The gas-fired boiler is usually equipped with the safety protection devices to ensure the safe boiler operation under pressure.

1) Set up the air preheater. One of the most effective measures to improve the thermal efficiency of thermal oil heater is to use an air preheater for heat recovery. 2) Use waste heat boiler for heat recovery. The waste heat boiler uses the waste heat in the flue gas exhausted from the thermal oil heater to heat water or generate steam.

The gas consumption of 10 tph gas-fired boiler is related to technical parameters. Such as heating surface layout, heat preservation effect, heat loss, water capacity, etc. The calculation formula of gas consumption of 10 tph gas-fired boiler is as follows: =10 tph gas-fired boiler output÷ thermal efficiency ÷calorific value of natural gas = 6,000,000 kcal ÷ 0.98 ÷ 8,600 kcal / h = 712 m3 Therefore, the gas consumption of 10 tph gas-fired boiler is 712 m3/ h The gas consumption of the above gas-fired boiler is calculated at full capacity. In practice, the gas consumption changes with the operation load and operation conditions. In addition, if thermal efficiency of the gas-fired boiler is different, the gas consumption is different, too. The higher thermal efficiency is, the lower gas consumption is.
