Factors affecting energy consumption index of cast iron boiler

2019-03-14 eight hundred and forty-one

China is carrying out a massive coal to natural gas campaign. The cast iron boiler has greatly reduced the dust infection, and the emission of toxic gases such as nitrogen oxides has been clamped. Energy consumption index is an important indicator for measuring cast iron boiler. After that, we can look at a pile of factors affecting the energy consumption index of cast iron boiler.

According to the investigation of relevant departments, the heat consumption of cast iron boiler mainly occurs in these two parts: unreasonable combustion air-fuel ratio and heat loss of flue gas emission. Reduction of flue gas emission heat loss will be done in cast iron boiler tail with chimney heat recovery and recovery assembly, or in FGR boiler based on better type.

Research on unreasonable combustion air-fuel ratio: traditional cast iron boiler should be equipped with injection type combustion engine, which can not be adjusted dynamically. There are two main reasons why the boiler is not suitable for air-fired boiler: the air-fired boiler can not be divided into two categories: one is that the air-fired boiler is not suitable for air-fired boiler; When the air flow is not up to the standard, it will cause insufficient combustion and the energy consumption index of cast iron boiler will decrease.
