china 8 ton coal steam boiler for chemical industries

1 ton gas boiler running on natural gas cost calculation users in the purchase of boiler equipment, in addition to considering the quality and price of the boiler, operating costs are also most concerned about. As a large industrial boilers special equipment, operating costs after start-up is not low. Today, small series to calculate the running costs of natural gas boiler, to help you better understand the gas boiler. On the whole, operating costs including natural gas boiler: fuel costs, utilities, labor costs, maintenance costs. Run 1 ton gas china 8 ton coal steam boiler for chemical industries 1 hour example to calculate the cost of running the boiler. 1, the cost of gas, 1 tons of gas steam boiler steam rated the amount of 1 ton / hour, different in different parts of the integrated natural gas quality and other factors, natural gas consumption in the 70-80 cubic meters / hour, according to our understanding, now on the market of natural gas the price of 3.5 yuan / cubic calculated (prices slightly floating), gas consumption is calculated according to 75 cubic meters. Gas Cost: 1 × 75 × 3.5 = 262.5 / hour 2, the cost of water, gas steam boiler 1 tons an hour to convert 1 ton 1 ton of steam into the water, because the middle of demineralized water and sewage water treatment needs, 1 ton of normal use of the steam boiler takes about 1.1 tons of water, according to our understanding, the market price is now floating around 3 yuan / ton. The cost of water: 1.1 × 3 = 3.3 yuan / hour 3, the cost of electricity, the main fuel gas steam boiler 1 ton electric burner position and pumps, other mostly weak. Burner using power 1.5KW, use the pump power of 1.4KW, other weak power use of about 1KW. During normal use of the boiler, electrical power is 0.65 times the full load power, calculate the total electric power (1.5KW + 1.4KW + 1KW) × 0.65 = 2.535KW. The electricity is $ 1 / calculation. Electricity costs: 2.535 × 1 = 2.535 / hour 4, labor costs, fast boiler into gas boiler market is the intelligent automatic high boiler plant, only coal fireman who patrol back and forth without the need to manually add fuel high intensity work. Fireman who according to 3000 yuan / month wage, working 12 hours a day, in two shifts. Labor costs: 3000 × 2 times / 30 days / 24 h = 8.33 yuan / 5 hours, gas boilers, and maintenance costs of model SZS fast WNS square type gas boiler in the factory after the quenching treatment and a full range of testing, failure rate Very low, response, post-boiler maintenance costs are reduced. If it is a gas station one ton steam boiler, the maintenance cost is about 2000 a year on it. According to 365 days a year, eight hours a day of computing time, the boiler operation cost per hour is: 2000/365/8 = 0.68 yuan. Combining these five aspects of the cost of inputs, it can be summed up 1 ton operating cost per hour of gas boilers: 262.5 yuan / hour + 3.3 yuan / hour +2.535 yuan / hour +8.33 yuan / hour +0.68 yuan / hour = 277.345 yuan / hour . In addition Xiao Bian also like to remind you that the above calculations are based on the cost of using boiler operating at full capacity, but due to the use of the boiler boiler enterprises have different needs, it may not be fixed to keep running at full capacity. Therefore, some of the actual running costs of the boiler than it is now calculated 277.345 yuan low. If you have more questions about natural gas boiler in the running cost, please direct online consultation fast boiler for more details boiler equipment!

Main china 8 ton coal steam boiler for chemical industries temperature abnormal phenomenon of how to do 1, main steam temperature anomalies alarm. 2, the rapid variation of the main steam temperature, a secondary damper frequently significantly reducing water operation. 3, starting superheat outlet steam separator above or below normal. 4, if the steam with water, the unit will water shock occurs. 1 reason, the fuel and water supply imbalance, the separator outlet temperature abnormality. 2, coal combustion conditions change or affect, such as excessive load lift; and pulverizing mill administration system abnormality stop; means automatically increase or decrease the failure rate is too large amount of wind and the like. 3, the central flame furnace changes, such as the bottom seal damage, W and inadequate flame downstroke. 4, the control failure by warm water, warm water flow rate reduction is abnormally reduced or increased. 5, feedwater temperature mutation. 6, does not match the wind coal. 7, the secondary combustion heating surface. 8, furnace coking or fouling seriously. 9, heating surface leakage squib. 10, flue gas damper opening degree is not normal. 11, coal sudden change occurred. 12, the uniformity of the powder feeding substantial change occurs. 1 process, failure caused by unit coordinated coal - water ratio should be immediately released coordinate offset, in accordance with the current load demand, with reference to the start of the steam superheat separator, and adjusting the amount of fuel corresponding to the amount of water, with one, two main desuperheating water rapidly steam temperature control in a normal range; when the coal - water ratio should avoid imbalance after coal and water while adjusting; when coal - water ratio is adjusted to further adjust the load after a relatively stable; contact maintenance processing timely. 2, when the water supply system fault condition occurs a significant disturbance furnace should pay attention and automatically coordinated working conditions, so as not to manual intervention, when not working properly coordinated and automated, should be manually adjusted, stable water flow, referring to separation according to the water flow steam superheat, the adjusted amount of fuel, with a secondary spray water rapidly controlling the main steam temperature within the normal range; contact maintenance processing timely. 3, due to rapid changes in load caused by the load change rate should be adjusted; load change caused due to protective operation or the like caused by heat load to be quickly adjusted to maintain the boiler pressure of the main steam stability. 4, by warm water automatic dysregulation, should be appropriate Save warm tone is switched to the manual may be an intermediate point of the feedwater control system be corrected for temperature if necessary, or the feedwater to switch control to manual control, due to lower lifting and lowering the load speed to prevent steam temperature, promptly contact a service process. 5, the boiler furnace cause severe fouling and coking of the main steam temperature anomalies can be corrected by an appropriate degree of superheat outlet steam separator start, adjust, and in a timely manner and the furnace heating surface sootblowing. When the platen superheater sootblowing or superheater outlet temperature is still above normal and a secondary reducing water damper fully open, to check the furnace and the combustion air distribution system is normal, the checking process to reduce still overtemperature unit load. 6, flue gas damper adjusted to an appropriate opening degree. 7, if the bottom seal after losing back to normal immediately. 8, to strengthen the turbine expansion, differential expansion, axial displacement of the shaft vibration and bearing temperature monitoring, if abnormal, the process according to the corresponding regulations. 9, after the above measures, if invalid, should immediately drop the load process. 10, in front of the main steam temperature main steam 50 ℃ drastically reduced within 10 minutes, should an emergency stop.

Hot water boiler is one of the important equipment for the district to provide our real estate company, and two gas hot water provide the fast boiler boiler flotilla of environmental performance, in full compliance with state regulations after smoke was detected in the rear of the boiler. And boiler operation is safe, stable, we use the very at ease. --customer feedback
