tube single drum steam boiler

Around the 1940s, the war promoted the development of technology, and in the case of urgent military and economic needs, led to the development and successful application of marine oil-fired boilers.

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.

Second, the boiler water temperature

Rated supply temperature and return water temperature gas hot water boiler, mostly marked in accordance with the standard GB3166-82. The actual boiler for hot water, return water temperature according to weather conditions during the heating and the heating requirements of the decision. The adjustment method for heating in winter, there is a change of mass of the boiler water temperature regulation, but also the amount of change of the boiler flow rate adjustment cycle; therefore, the hot water boiler water temperature can change according to need.

Gas boiler burners burn is linked to many factors, for example, there may be a way to let the boiler temperature is high, it has reached the upper limit of the allowable planning, so that the furnace temperature flue gas heat radiation of the burner enhanced combustion spout wall temperature is increased burning.
