For general type of gb asme en din superheater for steam boiler feed water hardness index it is very important, the level of boiler water hardness tends to affect fouling and corrosion problems later. If the gas boiler water boiler so that the boiler water hardness higher levels may occur due to evaporation scaling, hot water boilers and, relatively speaking, more susceptible to corrosion.
Low nitrogen emissions is one of the important decision-making environmental development of our country, under the general trend, low nitrogen gas boiler has become a darling of the market. According to our fast boiler understood that, since 2016, Beijing will expand the transformation of low nitrogen gas boiler, and then, one by one to keep up with our other provinces, more stringent emission targets, the transformation of low nitrogen gas boiler without delay.
Recently, Dongguan City, Guangdong Province, announced the embodiment of combustion facilities out of the transformation of coal-fired boilers. Continued efforts to implement air pollution control operations, blue sky to win the battle to raise the overall urban air quality, promote the construction of beautiful Dongguan.
Program execution object: the end of 2018 or for the gas central heating has been completed and all coal-fired boilers, furnaces, stove and other combustion facilities within the region.
Remediation program goal: to complete the gas before the end of 2018 has been for central heating or combustion facilities have been built out of regional coal-fired boilers and other renovation work. among them,
1, 2018 May 31, the gas supply has been built up, or central heating coal-fired boilers and other combustion facilities within the region, incorporating the first period regulation, must be completed before the phase-out renovation work in October 2018 31
2, June 2018 period from 1 July to 31 December 2018 for gas central heating area is built up or coal-fired boilers and other combustion facilities within the scope of the regulation into the second period, to be completed by 31 December 2018 out of the transformation.
Program remediation requirements:
1, the boiler must get out of the transformation of the city of Quality and Technical Supervision issued by the migration, retirement, cancellation of certificate or change a new boiler fuel use permit after; furnace, stove eliminated after the transformation of environmental protection must apply the change.
2, central heating is completed, it must use natural gas, liquefied petroleum gas, electricity and other clean energy combustion facilities outside the area out of coal-fired boilers, etc. after the transformation continued use.
3, central heating boilers planning area must use the central heating (gas) after the completion of the heating zone, will not have the heating conditions can use natural gas, liquefied petroleum gas, electricity and other clean energy as a transition.
4, into the "scattered pollution", high pollution and high emissions from industrial boilers and enterprise-wide to be eliminated.
5, for failure to complete boiler or eliminated within the rectification period, the Municipal Environmental Protection Bureau in accordance with the requirements of relevant laws and regulations and strict enforcement of its Municipal Quality Supervision Bureau will be canceled.
Shutdown of the furnace to discharge the water, the inside completely remove the dirt, rinse, drying in the furnace with Weihuo (be careful not to fire), and then the bulk quicklime 10-30 millimeters in diameter installed sub-plate, placed in the drum, without metal contact with lime, quicklime by weight, calculated to the drum 8 kilograms per cubic meter volume, then all manholes, hand holes pipe valve closed, checked every three months, such as crushed lime shaped component, i.e. the need to replace, should be re-run the boiler and the lime disk unloading.

Side note: larger boilers rely on the water-filled tubes that make up the waterwalls of the furnace to generate steam. The heated water rises into the drum. Here, saturated steam is drawn off the top of the drum. In most large industrial services, the steam will re-enter the furnace through a superheater to become superheated. Superheated steam isOnline chat
