Description

Condensing furnace capable of recycling condensed water and connected with flue in parallel

Technical Field

The utility model relates to the technical field of condensing furnaces, in particular to a condensing furnace capable of recycling condensed water and connecting a flue in parallel.

Background

The condensing boiler utilizes an efficient condensing waste heat recovery device to absorb sensible heat in high-temperature flue gas discharged by the boiler and latent heat released by water vapor condensation so as to achieve the purpose of improving the thermal efficiency of the boiler. The flue gas temperature is very high when ordinary boiler burns, about 130 degrees, has taken away a lot of heats, and the condensation combustion technology falls flue gas temperature to 50 degrees, becomes liquid with partial flue gas condensation, has absorbed the flue gas and has become the heat of liquid from gaseous, has just retrieved the heat that originally was taken away by the flue gas, so the thermal efficiency is a lot of higher than ordinary boiler.

The combustion of fuel produces large quantities of CO2, NOX and small quantities of SO2, which are released into the atmosphere and can cause greenhouse effects and the production of acid rain, which can have a damaging effect on the environment. The condensing boiler can conveniently remove harmful substances in the flue gas while condensing the water vapor in the flue gas, so that the condensing boiler has important significance for protecting the environment.

At present, the flue gas emission of the full-premixing condensation gas furnace on the market is mainly that a single smoke pipe is directly discharged, or a plurality of smoke pipes are discharged to a total smoke pipe, and then the smoke pipes are discharged by the total smoke pipe.

The existing smoke discharge mode has the following defects:

1. the condensed water is not provided with a recovery device, so that the smoke tube is required to be installed downwards, and the surrounding environment is influenced;

2. the condensate water is provided with a recovery device, the smoke tube is upwards installed, rainwater and condensate water in the smoke tube are accumulated in a backflow mode, and blockage is easily caused by impurities or icing, so that the use of the boiler is influenced due to unsmooth discharge of the condensate water;

3. when the ignition is carried out, the front flue gas and the rear flue gas are mixed in the main flue, and the front flue gas and the rear flue gas can increase the flue gas emission resistance of the rear flue gas after being ignited, so that the ignition efficiency is influenced;

4. the original structure is complex, the butt joints are more, and the requirement on the sealing performance is high;

therefore, how to design a condensing furnace capable of recycling condensed water and connecting a flue in parallel is important to solve the technical problems.
