Industrial Energy Saving Dzl Coal Fired Steam Boiler

Small electric industrial energy saving dzl coal fired steam boilers What are the benefits, features? First, electric and coal, oil steam generating comparative advantages and disadvantages: advantages and disadvantages of coal: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce about 6 kg steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of coal-fired boilers and human factors affected the Boilermakers, the real heat of the steam is converted to produce much smaller than the theoretical value, the heat utilization rate of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, to ban small coal-fired boilers is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than coal.

Recently, in Qinghai Province Jigzhi County Market Authority carried out a special inspection of boiler safety within the county, mainly in order to further strengthen the special equipment safety supervision, investigation and potential risks.

County Market Authority was held on June 8 special meeting to make arrangements for this special inspection work; the meeting, Secretary of this special inspections put forward specific requirements: Either the county government and relevant departments in accordance with the superior, all in the area to check boilers, boiler and disabled to look back, to verify the implementation of the rectification; the second is to designate a person to carry out checks to ensure that this special inspection into effect, produce results; the third is to check violations found to be severely dealt with according to law.

Subsequently, according to the spirit of the meeting, Jigzhi County Market Authority Board redoubling its efforts to carry out special inspections. 5 out of law enforcement officers were examined using 10 units. The county has been reported to stop the boiler After registering with and eleven inspection and verification. Focus on checking whether the boiler inspection, whether the registration, check whether safety accessories in place, whether fireman certificates and other issues, focusing on correct pressure boilers, waste heat and pressure tanks and other equipment as well as the use of pressure boiler overpressure operation and other illegal operations behavior, found hidden among all checks for disposal in accordance with law, to ensure the safe operation of the boiler county.

Next, the county will further increase the pressure in the boiler with supervision and do routine inspections and safety management, strengthen the use of units to pay a return visit found the problem of checks put in place to promote the use of the unit responsibility, and earnestly safeguard the life and property Safety.

The transformation of low nitrogen boiler should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
