冬天,不少人家用土暖气取暖。倘若土暖气设计或安装不当便会发生爆炸伤亡事故。 土暖气爆炸的原因在于没安装安全阀和跑风设备。当锅炉被点燃后,炉内温度逐渐增高。随着温度的增高、土暖气循环系统里的水不断变热,水分子变得活跃,到一定温度就会变成水蒸气,体积急剧膨胀。如果土暖气的循环系统没有给膨胀的 Winter, many people use soil heating heating. If the local heating design or improper installation will result in explosion casualties. Soil heating explosion is due to the installation of safety valves and running gear. When the boiler is ignited, the furnace temperature gradually increased. As the temperature increases, the water in the earth’s heating and circulating system becomes hotter and the water molecules become active. At a certain temperature, it becomes water vapor and its volume expands rapidly. If the soil heating circulatory system did not give expansion
