Guide: Since the national environmental protection requirements have changed from coal to gas, users have generally reported that gas-fired boilers have high operating costs and are too expensive to use. In order to reduce the operating cost of gas boilers, Yuanda Boiler optimized the type of gas boilers and developed and produced condensing gas boilers with good environmental protection effects. What is the working principle of a condensing gas boiler? Gas boilers can be used not only for industrial production, but also for heating. What are the differences between heating gas boilers and oil-fired boilers?

What are the differences between heating gas boilers and oil-fired boilers?

1. Working principle of condensing gas boiler

　　The working principle of the condensing gas boiler is to recover the energy in the hot flue gas (usually around 140℃) discharged after the boiler is burned through a certain device, and the recovered flue gas temperature is only around 60℃, so the thermal efficiency is probably improved. If the value is about 10%, it will naturally save about 10% of the gas. At the same time, in the energy recovery process, it can also reduce the emission of harmful gases and reduce environmental pollution. The core of the condensation technology is to reduce the heat loss of fuel combustion and efficiently absorb the heat energy generated by the fuel. At the same time, due to the condensation of the flue gas, the harmful substances in the flue gas are collected into the condensed water, reducing acidic substances and other pollutants into the air. emission.

2. the difference between heating gas boilers and oil-fired boilers

　　The fuel of the oil-fired heating boiler is oil (such as diesel, engine oil, kerosene, etc.), and the fuel of the gas-fired heating boiler is gas (such as natural gas, city gas, biogas, and liquefied gas, etc.). The equipment that depends on what fuel the boiler burns is called combustion Heating boilers equipped with gas burners are called gas heating boilers, and heating boilers equipped with oil burners are called oil heating boilers. The difference between oil heating boilers and gas heating boilers lies in what fuel burners are used.

The working principle of condensing gas boiler and the difference between oil and gas heating boilers are introduced above. When using oil and gas boilers, fuel should be selected reasonably to minimize boiler operating costs and ensure profits. At the same time, when choosing a boiler, the user must first implement the local environmental protection requirements to ensure that the boiler purchased meets the local environmental protection requirements, so that the boiler can be purchased, installed and used smoothly.
