2.1 用户实际对热能的需求量
2.1 user actual demand for heat
用户使用锅炉不外乎用蒸汽或热水去制冷、采暖、消毒、洗涤或工艺上加热其他物质,
这首先要知道需用多少热水(蒸汽)才能满足需要。一般情况下对工艺需用的蒸汽量,设
计院在设计时通过工艺的计算有一个明确的量的要求。对热能的需求量确定之后,选用锅
炉时,可按其标准的蒸发量选取。进行选择同时要考虑所选锅炉的适应性,因为燃气燃烧
器由于气源不同,其热值、压力均不相同。
Users with steam or hot water boiler is nothing more than to refrigeration, heating, disinfection,
washing or process heating on other materials, the first to know need how much hot water (steam)
to meet the need. Normally steam for process need, design institute through the process of
calculation in the design of have a definite volume requirements. After the determination of heat
demand, when choosing boiler, can be according to the standard selection of evaporation. Choose
want to consider the adaptability of the selected boiler at the same time, because the gas burner
because air is different, the calorific value and pressure are not the same.
2.2 海口环保对锅炉排放的要求
2.2 environmental haikou for boiler emissions requirements
为有效地保护环境,要防止边治理污染边制造污染。锅炉烟气是主要的大气污染源之
一,因此我国环境保护局和国家技术监督局于 1992 年 5 月发布了《锅炉大气污染物排放
标准》(GB13271-91),该标准对原始含尘浓度,锅炉烟尘允许排放浓度及 SOX,NOX
最高允许排放浓度,分别根据一、二、三类地区对环境保护的不同要求做了详细明确的说
明和规定。
To effectively protect the environment, preventing pollution and polluting. Boiler flue gas is
the main source of atmospheric pollution, therefore our country environmental protection bureau
and the state bureau of technical supervision issued in May 1992 by the boiler air pollutant
emission standard "(GB13271-91), the standard of the original dust concentration, boiler smoke
