Which type of 10 ton industrial steam boiler has the lowest operating cost? How to choose an industrial specific boiler?
Which type of 10 ton industrial steam boiler has the lowest operating cost? How to choose an industrial specific boiler?
1. Gas steam boiler
The rated steam output of a 10 ton gas steam boiler is 1t/h, while a 10 ton gas steam boiler requires a consumption of 700 to 800 cubic meters of natural gas. Calculated based on 750 cubic meters of natural gas, each cubic meter of natural gas is calculated at 3 yuan/cubic meter (natural gas prices vary in different regions)
The gas cost of a gas steam boiler is 750 × 3=2250 yuan/hour.
A 10 ton gas-fired steam boiler needs to generate 10 tons of steam. Normal use of a steam boiler requires 10.1 tons of water for 10 tons of steam, which is calculated at 3.5 yuan/ton.
The water cost for a gas steam boiler is: 10.1 × 3.5=35.35 yuan/hour.
The burner and water pump of a 10 ton gas steam boiler are the main power consuming parts. The power of the burner is 15kw, the power of the water pump is 13.7kw, and the other power consumption is 10kw. Under normal circumstances, the boiler’s power consumption is 0.65 times the full load power, and the electricity fee is calculated at 1 yuan.
The electricity cost for a gas steam boiler is: (15kw+13.7kw+10kw) × 0.65 × 1=35.2 yuan/hour.
2. Biomass steam boiler
A 10 ton biomass boiler normally consumes 1500 kilograms of biomass, which is calculated at 800 yuan per ton of biomass.
The fuel cost of biomass steam boiler is: 800 × 1.5=1200 yuan
A 10 ton biomass steam boiler, like a gas steam boiler, requires 10.1 tons of water for steam production.
The water fee for biomass steam boiler is: 10.1 × 3.5=35.35 yuan/hour.
The hourly power consumption rate of a 10 ton biomass steam boiler is approximately 67 kW, so the electricity cost of the biomass steam boiler is 67 × 1=67 yuan/hour.
3. Electric heating steam boiler
The fuel for electric heating boilers is mainly electricity, and a 10 ton electric heating boiler requires 7500kw of electricity, so the electricity cost for electric heating steam boilers is 7500 × 1=7500 yuan/hour.
The water fee for an electric heating steam boiler is: 10.1 × 3.5=35.35 yuan/hour.
In addition to fuel costs, water and electricity costs, there are also labor and maintenance costs. The labor cost is calculated at 3000 yuan per month and 10 hours of work per day, with a cost of 10 yuan per hour.
Under normal use and maintenance, the maintenance cost is calculated at 5000 yuan per year, requiring a maintenance cost of 1.37 yuan per hour.
Based on the above content, let’s take a look at which comprehensive operating cost is the most cost-effective!
The operating cost of gas steam boiler: 2250+35.35+35.2+10+1.37=2331.92 yuan/hour
The operating cost of biomass steam boiler: 1200+35.35+67+10+1.37=1313.72 yuan/hour
The operating cost of an electric heating steam boiler is 7500+35.35+10+1.37=7546.72 yuan/hour
