With the arrival of winter, smog is becoming more and more serious all over the country. In some places, the State Environmental Protection Department has taken a series of measures such as forcibly shutting down coal-fired boilers in order to control pollution. For some enterprises, the necessary coal-fired steam boilers must be closed, and other energy-saving boilers need to be replaced. This virtually increases the operating cost of enterprises, because the operating cost of new boilers such as gas-fired boilers is twice or even more than that of coal-fired boilers.
In the business consultation with some customers, it was learned that after the coal-fired boiler was forced to shut down, there was no steam, and the enterprise had to stop production. For the survival of the enterprise, only replace the boiler to choose natural gas boiler, oil fired boiler, electric heating boiler and biomass particle boiler. At present, only natural gas boilers are mainly selected for the market. The reason is that natural gas boilers are full-automatic gas-fired boilers without any pollution. However, in reality, many enterprises facing the need to replace boilers do not have natural gas pipelines in place, and some enterprises do not have natural gas pipelines at all, let alone natural gas ventilation. This is a big obstacle at present.
The cost of oil fired boilers and electric heating boilers is higher, and many small and medium-sized enterprises simply can't afford it. The calorific value of biomass particle boilers is too low, and the thermal efficiency of boilers is too low, and the gas consumption often can't keep up. For many reasons, gas-fired boiler is called the main alternative to coal-fired boiler.
In fact, while the state vigorously forces the closure of coal-fired boilers, it should consider small and medium-sized enterprises, do a good job in the foundation, lay natural gas pipelines in place, and then the price department will appropriately reduce the cost of gas to reduce the burden of natural gas boiler users. This is the choice to control air pollution and the main measure to curb smog, rather than forcibly shutting down the operation of coal-fired boilers.
