CTIF-Ulmer氏换热式热风炉的操作原理就是以换热器代替化铁炉烟囱,充分利用全部煤气,煤气无需预先除尘。此种双壁换热器较之普通管式换热器构造简单,操作容易。换热器位于化铁炉炉顶,化铁炉废气由换热器中央穿过,而热空气则在双壁中间穿过,均由下向上流动,换热器共有三种功能:①充作燃烧室,②充作换热器,③充作烟囱。如此,既可利用煤气的导热,又可利用其辐射热。由于煤气空气同向流动可避免过热现象。在风温保持400℃的情况下内壁仍可使用普通锅炉钢板制造。
The operating principle of the CTIF-Ulmer heat exchangers is to replace the furnace shaft with a heat exchanger, making full use of the entire gas without the need for pre-dusting. This double-wall heat exchanger than ordinary tube heat exchanger structure is simple, easy to operate. The heat exchanger is located at the top of the iron furnace, and the waste heat of the iron furnace passes through the center of the heat exchanger. The hot air passes through the middle of the double walls and flows from the bottom to the top. The heat exchanger has three functions: Combustion chamber, ② as a heat exchanger, ③ as a chimney. So, both the use of gas heat, but also the use of its radiant heat. As the gas flow in the same direction to avoid overheating. In the case of the air temperature is maintained at 400 ℃ can still use ordinary boiler plate manufacturing.
