The waste heat boiler can recovery waste heat and use it to produce heat and electricity for production or civil life. High temperature furnace slag waste heat Such as blast furnace slag, converter slag, electric furnace slag, etc. the slag temperature is above 1000 ℃, and it takes away 20% of total heat.
Boilers provide radiant heat, which warms objects in a room. In contrast, a forced air furnace warms the air in a room, which means objects absorb heat more slowly. Some people prefer boilers because they can set their thermostat at a lower temperature and the radiant heat makes the room feel warmer than the actual air temperature.
