Examples

Fig. 1 is a schematic structural diagram of an embodiment of a horizontal three-pass condensation integrated steam generator of the present invention. As shown in fig. 1, a horizontal three-pass condensation integrated steam generator comprises an evaporator, a condenser and an economizer. Be provided with stove courage 1 in the evaporimeter, stove courage 1 top is provided with evaporating chamber 6, and many inlet tubes 8 are connected to the evaporating chamber, and inlet tube 8 communicates with the delivery port of external moisturizing case, and inlet tube 8 sets up on the inner wall of stove courage 1. High-temperature flue gas generated by the sufficient combustion of the low-nitrogen combustor and water in the water inlet pipe 8 are subjected to radiation heat exchange to absorb a part of heat, so that the water entering the evaporation chamber 6 is heated, and the temperature of the water entering the evaporation chamber 6 is increased. Meanwhile, a water inlet III 11 of the evaporation chamber 6 is connected with a water replenishing tank and can provide water after heat exchange through the condenser 5 and the energy saver 9 for the evaporation chamber 6. The evaporation chamber 6 is provided with a steam outlet 7, and high-temperature steam generated in the evaporation chamber 6 can be discharged outwards through the steam outlet 7 and converted into other forms of energy or directly supplied to people for use. The rear smoke chamber is arranged behind the furnace pipe 1 and communicated with a hearth in the furnace pipe 1, and high-temperature smoke enters the rear smoke chamber from the hearth to complete a first return stroke.

An energy saver 9 is arranged on the outer side of the furnace pipe 1, a threaded smoke pipe is arranged in the energy saver 9, the threaded smoke pipe in the energy saver 9 is connected with the rear smoke chamber through a flue, and high-temperature smoke in the rear smoke chamber enters the energy saver 9 through the flue and enters a second return stage. High-temperature flue gas flows in the threaded flue in the energy saver 9, so that the retention time of the flue gas in the energy saver 9 is prolonged, and compared with a light pipe with the same length, the radiant heat exchange efficiency is improved.

A condenser 5 is arranged above the energy saver 9, and a threaded smoke pipe in the energy saver 9 is communicated with the condenser 5 through a flue.
