For a coal-fired steam stove, because of the different fuels he uses, the advantages and disadvantages of the stove are obvious. Disadvantage: It is impossible to achieve automatic control. If the steam-using equipment does not use steam continuously and smoothly, the instantaneous steam consumption fluctuates greatly, and the steam generated by hot blast stove can only be discharged when the bottom valley of the steam-using equipment is used, which is a serious waste. Low efficiency, although theoretically more than 5000 calories per kilogram of coal can be generated, but due to the limitations of coal-fired hot stove and the influence of artificial factors by the hot stove workers, the real heat conversion to steam is far less than the theoretical value, and the heat utilization rate is about 60%. Professional operators are needed and the cost of manpower is high.
It is not in line with the requirements of modern environmental protection, and banning small coal-fired hot blast stoves is the general trend.
Advantages: Coal is the most economical energy source. Coal can produce more than 5,000 calories per kilogram, and can produce about 6 kilograms of steam (theoretical value). It is more economical than electricity, fuel and natural gas.
Understanding the advantages and disadvantages of coal-fired steam stove is very helpful to our work, we have enough knowledge of him, in order to be able to have the greatest help.
