The functioning time is 10 hours daily, 300 days every year.
So cattle feed pellet making machine is ￥ 43500.
Yearly labor price.
The job has 2 shifts a day.
As the gas central heating boiler has higher automation, and also the procedure is straightforward, it needs only 1 firefighter.
The wage is ￥ 3000 each month, so the yearly labor expense is ￥ 72000.
Annual maintenance expense.
The maintenance work of a gas central heating boiler is very little, the price is low.
Mean the maintenance price is 1% of the devices cost, then it is ￥ 2100 yearly.
By computation, the annual running expense of a biomass boiler is ￥ 3,047,100.
Verdict.
In terms of the equipment price, biomass central heating boiler is more than natural gas central heating boiler. In terms of the yearly running price, as natural gas boiler has higher automation degree, requires less power intake tool, and less upkeep, the electric cost, labor cost and maintenance expense is less than that of biomass central heating boiler. Yet taking into consideration the high cost of gas, the overall operation cost of gas central heating boiler is more than that of biomass boiler.
Environmental result.
Biomass fuel.
Researchers gauged the exhaust of smoke, SO2 and NOx in 2 biomass central heating boiler.
These 2 boilers has similar dissipation capacity. Both of them are not furnished with sulfur and also nitrate getting rid of gadget. However the first one is outfitted with a bag-type dirt enthusiast, as well as the second one is outfitted with a film-type dust collection agency.
