All over the country has introduced a different atmospheric emission standards. Such as Beijing, Henan, Sichuan and Hebei requirement is 30mg nitrogen oxide emissions; Tianjin, Shanghai and other places asking for is 80mg of nitrogen oxide emissions. If you do not understand the local environmental policy, you can contact the local environmental protection department consulting, identify and then buy gas top heating boiler. This will avoid situations where buy boiler emissions of non-compliance can not use a normal appearance.

Refers to natural circulation top heating boiler in the boiler evaporation system, using the density difference between water and a mixture of soda precipitation of the riser pipe as a driving force, the working fluid circulation flow established (also known as water cycle), the evaporator heating surface being cooled boiler. With the increase of the boiler capacity, pressure natural circulation boiler have been increased.

Fangkuai Boiler is a clean-up top heating boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.

In summary, the difference between the atmospheric pressure hot water top heating boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, but the most important is to combine their own needs to consider, select which type of boiler products.
