Production of 1 ton of steam, respectively, how much coal, biomass particles, biomass briquettes?

With the treatment of coal-fired boilers, many customers asked me to change the biomass, and coal compared to the bottom of the cost of what circumstances, today I give you analysis, so that we have an intuitive impression

How much fuel does 1 ton of steam need? Biomass and coal are low at the end of the cost

1,1 tons of steam enthalpy of about 64 million kcal, that is, a ton of steam needs 64 million calories

2, coal calorific value of 5,000 kcal / kg, priced at 0.7 yuan / kg, coal-fired boiler thermal efficiency of 65%, the actual use: 5000X65% = 3250 kcal / kg.

1 ton of steam how much coal needed: 640000 ÷ 3250 = 197 kg, 197 × 0.7 = 137 yuan

3, the biomass particle calorific value of 4200 kcal / kg, priced at 0.85 yuan / kg, biomass boiler thermal efficiency of 85%, the actual use: 4200 × 85% = 3570 kcal / kg.

1 ton of steam how much biomass particles: 640000 ÷ 3570 = 179 kg, 197 × 0.85 = 152 yuan

4, biomass briquetting calorific value of 3800 kcal / kg, priced at 0.55 yuan / kg, biomass boiler thermal efficiency of 85%, the actual use: 3800 × 85% = 3230 kcal / kg.

1 ton of steam how much biomass briquetting: 640000 ÷ 3230 = 198 kg, 198 × 0.55 = 109 yuan

5, the conclusion, professional biomass boiler and coal-fired boiler 1 ton of steam costs are as follows

Coal: 137 yuan, burning biomass particles: 152 yuan, burning biomass briquetting: 109 yuan,
