When users buy biogas steam boilers, they should not only consider the purchase cost in the early stage, but also the long-term operation cost of the boiler. The energy saving effect of a biogas boiler determines the long-term operation cost of the boiler, so enterprises should pay attention to it. The biogas fired boiler cost includes: fuel cost, water and electricity cost, labor cost and maintenance cost. Taking one ton methane steam boiler as an example, the operation cost of boiler is calculated. The gas cost of 1 ton biogas steam boiler rated output of 1t/h, comprehensive regional biogas quality factors, biogas consumption of 70 to 80 cubic meters, biogas price in accordance with 3.5 yuan/cubic calculation (price has a floating) to take the large gas consumption of 75 cubic meters, biogas cost: 1x75x3.5=262.5 yuan/hour.
1 ton steam boiler an hour can make 1 ton of water into 1 ton of steam, due to sewage and softening water and other reasons, in the normal use process of 1 ton of steam needs 1.1 tons of water, water according to 3.6 yuan/ton calculation, water cost is: 1.1×3.6=3.96 yuan/hour. The main electric parts of this series of boiler products are burner and water pump. The other parts are weak current. The power of burner is 1.5KW, the power of water pump is 1.37KW, and the other weak current is 1KW. In the normal operation of the boiler, the power consumption is 0.65 times of the full load power, and the calculated power consumption is (1.5KW + 1.37KW + 1KW) × 0.65 = 2.52KW. The electricity charge is 1 yuan/kWh. The electricity cost is: 2.52KW *1 yuan/kWh =2.52 yuan/hour.
The biogas fired boiler cost is controlled reasonably. The boiler is fully automatic boiler guard, which only needs workers to inspect it back and forth. Two shifts, an inspector a month according to the salary of 3000 yuan. Working 12 hours a day, the cost of one hour is :3000×7 person-times /30 days /24 hours =8.33 yuan/hour. This series steam boiler runs stably, the failure rate is low, the maintenance cost is less. Calculated according to the annual maintenance cost of 2000 yuan, the maintenance cost per hour =2000 yuan ÷ December :30 days +24h=0.23 yuan.
In summary, the operating cost of 1 ton biogas steam boiler per hour is as follows: 262.5 + 3.96 + 2.52 + 8.33 + 0.23 =277.54 yuan/hour. The operation cost is not accurate data, it needs to be calculated according to the consumption difference of each region and the objective factors of boiler operation. From the above data, we can find that gas fired boiler operation cost is the main fuel costs, more than about 90% of the total cost, according to steam boiler according to every day need to steam, hot water boiler running time by date, the above are converted into full load operation time, with the unit capacity boiler gas consumption and gas price, so can buy boiler season is very important, effective control of boiler operation The cost of line.
With the implementation of environmental protection policy, the condensing gas boiler produced by Zozen Boilers has a high application in various industries. Helped many well-known enterprises to achieve “coal to gas”, effectively improve the user benefits. Biogas fired steam boiler is more detailed introduction of sewage treatment process of biogas utilization, provide textile, printing and dyeing, paper, food, rubber, plastic, chemical, medicine, steel, metallurgy and other industrial products processing process needed steam. I plant boiler use effect is good, energy saving and consumption reduction is significant, get the user’s consistent high praise!
The biogas fired boiler cost is reasonable, and the gas consumption per hour is equal to the power tree time of gas-fired boiler/fuel calorific value/boiler thermal efficiency. Influenced by the calorific value of biogas: different fermentations, then the calorific value of biogas produced is also different, so we must first find out the specific calorific value. To be sure, biogas doesn’t have the same calorific value as natural gas, usually around 5,000 kcal. Affected by boiler operation efficiency: this point is very well understood, the furnace operation efficiency is high, then the fuel combustion is more sufficient, natural overall consumption of fuel is less. So, if you want to consume less methane, choose a more efficient stove. For example, we can choose the biogas boiler produced by Zozen Boilers, which can achieve a design thermal efficiency of 98%.
