（DB44/765-2019）

Recently, Guangdong Province issued a "Boiler Air Pollutants Emission Standards" (DB44 / 765-2019) (hereinafter referred to as the "standard").

A "standard" in the context of the implementation province domain for coal, oil, 65 tons of steam per hour and the material forming steam boiler burning fuel gas and raw, hot water boilers of various capacities and organic heat carrier boiler; stoker of various capacities, stoker furnace.

Second, the implementation of the emission limits of air pollutants specified in Table 1 of the boiler since July 1, 2019, since 2020 July 1 implementation of air pollutant emission limits specified in Table 2.

Third, the new boiler since April 1, 2019 (the date of the present embodiment standard) executed from air pollutants emission limits specified in Table 2.

Fourth, not the implementation of clean energy transformation of 35 tons of steam per hour and higher coal-fired boiler from January 1, 2021, implementation of the provisions of air pollutants emission limits in Table 3 in particular.

First, check whether the diameter in claim australian boiler manufacturers pressure hot water boiler is the same as the opening to the atmosphere, under any operating conditions, the water level in the boiler are zero gauge pressure boiler. Therefore, before use, the user should check for new boilers, in particular, check whether the diameter to meet the requirements. Further, the communication tube should be prohibited in any valve provided to ensure smooth takeover. Generally, professional supply of pressure hot water boiler will spray "pressure boilers may not use pressure and hot water outlet temperature should not exceed 90 ℃" warning labels in the apparent position of the furnace. Second, installed by professionals, debugging initial purchase use, pressure hot water boiler manufacturer will recommend the installation and commissioning of the boiler by professionals to be responsible. Once operational, non-professionals are not allowed to change the structure of the boiler, free installation system piping, valves. At the same time, it should also be noted that must not be converted boiler pressure hot water boiler pressure. Third, to ensure that sensitive and reliable boiler safety accessories

Effects of heat loss is mainly affected by the exhaust gas temperature and excess air coefficient α, the excess air coefficient α is too large, will cause an increase in the amount of smoke, take away more heat, it should be the premise of ensuring the combustion efficiency of the australian boiler manufacturers as possible reduce the excess air ratio, it can be reasonably arranged through the burner, strict debugging operation, its structure and the characteristics of the boiler, the type and characteristics of the fuel matched to ensure that the flame in the furnace is full, the fuel combustion.

Environmental performance a: large combustion chamber space, make full use of radiation heat transfer, with high quality and reliable imported burner, the fuel can get complete combustion, significantly reduce emissions of harmful smoke constituents. Testing by the legal department, steam, hot water australian boiler manufacturerss comply with national environmental requirements, is the ideal environmentally friendly products.
