What do I need to know about steam equipment replacement and retrofit in the paper industry?

Paper industry is also one of the industries that need more boiler equipment, because there are many parts of the paper process requires a large amount of steam to carry out drying, molding and so on. In recent years, with the domestic environmental protection of small-tonnage coal-fired boiler ban strategy, so that the application of many coal-fired boiler companies must be coal-fired boiler transformation, or again to buy new environmentally friendly boiler equipment.

Paper mill boiler coal to gas is a key trend in the transformation of coal-fired boilers, but also more enterprises to transform a more, especially in the gas coverage of the region, the boiler coal to gas is still prevalent. Today we will take you to understand how to choose.

1, mechanized laminar coal-fired boilers, to be converted to gas steam generator, should first take down the front and rear arches, in addition to consider lifting the bottom heating surface, in lieu of the grate, to avoid overheating and burning of the grate;.

2, through the heat transfer calculation of the furnace, to determine the geometry of the furnace, the middle position of the furnace flame, and pour the furnace again. In order to ensure that the steam generator after the arch pipe to avoid the flame in the middle of the position, the original after the arch pipe in the existing slope under the premise of raising;.

3, to avoid the furnace burst, coal-fired furnace into a gas-fired steam generator, when the fuel oil atomization is not good or insufficient combustion of gas in the furnace or the tail in the heating surface convergence, but also fire or burst, so the appropriate parts of the boiler should be installed in the protective door, in addition to automated control should be added to start the program control and flame failure protection devices to ensure safe operation of the boiler.

4, burner selection and layout and furnace form is closely related, should make the furnace flame fullness is relatively good, do not form a dead airflow. Burner arrangement should also take into account the gas piping and duct layout is reasonable, the use, inspection and maintenance is convenient.

Through the above you can know that the paper mill boiler coal to gas must lift the bottom heating surface, pour the furnace body again, lift the plateau after the arch pipe, device protection door, start program control and flame failure protection device, reasonable choice of burner.
