利用燃气快速热水器在不同使用工况下，烟气中有害气体含量及厨房环境测试数据，分析了热水器排放及其对厨房环境的污染情况。通过分析得出结论，提醒人们在使用热水器时应注意的问题。模拟工况有以下几种：厨房空气流通情况下热水器正常使用；厨房空气不流通情况下使用热水器；厨房空气流通情况下，热水器烟道部分堵塞；厨房空气不流通情况下，热水器烟道部分堵塞。 The use of gas-fired water heaters under different conditions of use, the content of harmful gases in the flue gas and kitchen environment test data, the analysis of the water heater emissions and the pollution of the kitchen environment. Through analysis, the conclusions are drawn to remind people to pay attention when using water heaters. The simulated conditions are as follows: the water heater is normally used under the condition of kitchen air circulation; the water heater is used when the kitchen air is not in circulation; the water heater flue is partially blocked when the kitchen air flows; the water heater flue is partially blocked when the kitchen air is not in circulation .
