The economizer flue gas is in the right side space top-down preheats the water in the spiral coil, and the back is gone into the left side space from the bottom and then upwards heats the water in the spiral coil in the left side, and in the flue gas pipe that enters into the tail gas purifying box from the left flue gas pipe in top at last, the flue gas directly let in the scavenging solution (generally be water), then is taken out by the fan on the blast pipe and discharges.

The utility model discloses following beneficial effect has: the water that produces steam utilizes the waste heat of flue gas to preheat at first at the spiral coil pipe in the energy-saving appliance after, can absorb the heat of flue gas, reduces heat emission and reaches the environmental protection requirement, can also realize preheating water, and the temperature high point that gets into in the interchanger like this is convenient for heat and is produced steam, the energy saving, and is energy-concerving and environment-protective. The flue gas circulates about the interchanger forms, increases the route, and effective parcel lives the hot plate, and the extension flue gas stays heating time, absorbs the heat more abundant, and the effect is better, and burning living beings, tail gas are more clean, and living beings and air mixing get into simultaneously, and the burning is more abundant like this, and is energy-concerving and environment-protective.
