Background
The wall-mounted boiler is a gas wall-mounted boiler, which is called a gas wall-mounted heating boiler for short and is a water heater using natural gas as energy. The wall-mounted gas stove has a powerful household central heating function, each room can be set at a comfortable temperature at will according to requirements, and large-flow constant-temperature sanitary hot water can be provided for household bathing and kitchen places.
The wall-mounted furnace with the condensing heat exchanger has high heat efficiency, saves energy and is environment-friendly and is more and more popular among users. The principle of condensation refers to that high-temperature flue gas releases heat in the process of meeting condensation, and the condensation technology is to fully collect the heat so as to increase the heating heat. Energy in the waste gas is recycled by condensing the flue gas, and the net heat value is increased, so that the thermal efficiency reaches 107%, the gas quantity is reduced, the energy consumption is greatly saved, and the energy consumption is saved by 15% compared with a common wall-mounted furnace.
After the gas of the wall-hanging stove with the condensing heat exchanger is completely combusted, the smoke is completely cooled to the original temperature, and the water vapor in the gas is discharged in a condensing state to generate heat. The existing condensing wall-hanging stove has the following problems: 1. the flue gas contains three-atom gas RO, wherein the main component of RO is CO2And SO2Therefore, the condensed water contains acid, and the common copper pipe is not acid-resistant in heat exchange and is easy to corrode; 2. the existing wall-mounted furnace structure with the condensation heat exchanger has the advantages that the heat exchange tube only exchanges heat with high-temperature flue gas regardless of top burning or side burning, but the heat on the wall surface of a combustion chamber is not fully utilized.
