電熱水燃氣鍋爐是一種燃燒清潔能源天然氣產(chǎn)出熱水的工業(yè)鍋爐，隨著國家燃煤整改政策的相繼實施，這種鍋爐的使用及推廣力度逐漸加大。由于鍋爐是特種設(shè)備，因此為了防止使用中出現(xiàn)安全事故，需要在設(shè)計的時候設(shè)計安全保護系統(tǒng)。燃氣熱水鍋爐設(shè)計有超溫、超壓、缺水、檢漏、熄火等多種保護功能，鍋爐運行安全可靠。
1、超溫報警和連鎖保護裝置
超溫報警裝置這個保護裝置一般安裝在熱水熱風(fēng)爐的出口處，當(dāng)燃氣熱風(fēng)爐水溫超過規(guī)定的水溫時，自動報警，提醒司爐人員采取措施減弱燃燒。超溫報警和連鎖保護裝置連鎖后，還能在超溫報警的同時，自動切斷燃料的供應(yīng)和停止鼓、引風(fēng)，以防止熱風(fēng)爐發(fā)生超溫而導(dǎo)致設(shè)備損壞。
Over-temperature protection device alarm device that is usually installed at the exit of hot stove, gas stove when the water temperature exceeds a predetermined temperature, automatic alarm to alert staff to take measures to weaken the burning fireman. After over-temperature alarm and interlock protection device chain, but also at the same temperature alarm automatically cut off the fuel supply and stop the drum, the wind, in order to prevent the occurrence of over-temperature stove caused damage to the equipment.
2、高低水位警報和低水位連鎖保護裝置
當(dāng)熱風(fēng)爐內(nèi)的水位高于最高安全水位或低于最低安全水位時，水位警報器就會自動發(fā)出警報，提醒司爐人員采取措施防止事故發(fā)生。
When the water level inside the stove higher than the highest safety level or below the minimum safe level, the water level alarm will automatically alerts to remind fireman who take measures to prevent accidents.
3、熄火保護裝置
當(dāng)燃氣熱風(fēng)爐爐膛熄火時，熱風(fēng)鍋爐熄火保護裝置作用，切斷燃料供應(yīng)，并發(fā)出相應(yīng)信號，提醒操作人員注意。
When the gas stove flame furnace, hot air boiler flameout protection device acts to cut off the fuel supply, and issued a corresponding signal to alert the operator attention.
