Chain stove ； Pulverized coal furnace ； fluidized bed boiler ； Which boiler is better, such as coal-water slurry boiler, equipment investment and future operating costs and other benefits comparison! Because our company operates seasonal production and only produces for 8 months a year, we originally had three chain steam boilers.: 1T (furnace age 10 years); 4T (furnace age 8 years); 6T furnace age (furnace age 5 years). They are all boilers produced in Changsha. The efficiency of the three boilers is not high. It used to be enough to burn only one 6T boiler in winter, but now we have to burn two.: 4T;6T will do. The leader has been considering whether to replace a 10T boiler or to retrofit three chain boilers to save energy. I wonder whether the retrofit will be effective and cost-effective? Thank you for your suggestions. The chain furnace is more economical and practical!
I think if you want to use coal as fuel, you should choose a chain stove. It is relatively economical, but it depends on whether the environmental protection standards are met. At present, coal-water slurry boilers meet environmental protection standards, but their operating costs are relatively high compared with solid coal.
To be honest, chain boilers are the most practical and the cost is relatively low. Boilers such as fluidized beds require a relatively large investment. The most important thing to buy depends on the capabilities and needs of your company.
The cheapest initial investment is the chain furnace, which is estimated to be only about 100,000.； The investment for other furnace types is relatively high. If you have a pulping plant nearby, you can consider using coal-water slurry.

Reply 6# lg1968 If it is used to produce saturated steam, it will not be very expensive, at most it will cost about 100,000 to 200,000 yuan. I have visited and found that many places make such chain furnaces. However, the efficiency of this kind of stove is very low, it seems to be only more than 70%.
Chain stove: The initial investment is relatively small, the operation is stable, the operation is simple, and subsequent maintenance is easy. The boiler efficiency is low. If environmental protection requirements are high, a special desulfurization and dust removal device needs to be installed. circulating fluidized bed boiler: Wide fuel adaptability, low pollutant emissions, and no need to set up a special desulfurization device. The boiler has high combustion efficiency, high initial investment and high operating requirements.
Just use a chain furnace. Others are either flashy or have high operating requirements and are not very economical and practical.

Reply to 1# lg1968 As for the chain furnace, the thermal efficiency is about 80%. There seems to be no need to use a fluidized bed boiler. Although the thermal efficiency is high, the cost is relatively expensive. In fact, you can consider using a gas boiler. Nowadays, natural gas is cheap and pollutes less. * * There should be relevant policy support, right? Anyway, when I was doing sales, I found that the demand for gas stoves is relatively high now. :)
