How to change coal-fired boiler to natural gas boiler?

How to change the coal boiler to natural gas boiler?

I. Boiler selection

How to change coal to natural gas involves many aspects, such as boiler body, gas supply system, air system, burner system, ignition system and smoke exhaust system.

1. Under the condition that the total heat demand is constant, the total tonnage of the boiler after changing to natural gas can be constant; If the total heat consumption increases or decreases, it needs to be adjusted in time to ensure the heat consumption. Please consult professional boiler manufacturers here. The capacity of ZOZEN gas boiler covers 1-130t/h, meeting the needs of most users.

2. The environmental protection standards of gas-fired boilers and coal-fired boilers are different. How to change the boiler to natural gas? You need to know the local environmental protection policies first.

3. After the boiler is converted to natural gas, because the fuel is cleaner, it is only necessary to adjust the combustion system to meet the discharge standard, without using desulfurization, denitrification and dust removal systems.

4. Besides considering how to change the boiler to natural gas, measures can be taken to save energy in the operation of natural gas boiler. At the same time, the energy-saving measures of natural gas boilers can also reasonably recover the condensed water in the heating system and recycle the heat of the condensed water.

II. Upgrade the boiler room

Although the gas boiler has less fuel storage space, but more gas pipelines are installed and transported, so corresponding safety measures need to be taken. Therefore, upgrading the boiler room is one of the important aspects in how to change the coal boiler to natural gas boiler:

1, according to the reliability of the gas source and the importance of the boiler load, determine whether to adopt the way of preparing for combustion and the corresponding fuel reserve.

2, according to the gas pressure and usage, determine whether it is necessary to set up a pressure regulating station.

3. Shut-off valves should be installed on the main pipe leading into the boiler room, and explosion-proof type should be used as far as possible for the relevant electrical and mechanical equipment of the boiler room.

4. Set gas concentration alarm device.

5. Corresponding standards and specifications should be implemented in the process of changing the coal boiler to natural gas boiler.
