20ton heavy oil fired steam generator

It is understood that around prevention and control of air pollution, ecological Environmental Protection Office of Shaanxi Province has formulated the "Boiler Air Pollutants Emission Standards" ( "Standards"), amended the "off key industries in the region of atmospheric pollutant emission limits." In the future, biomass, alcohol fuel boiler emissions also be included in "Standards".

"Standard" is to integrate and improve the local air emissions standards boilers. "Standard" for the scope of the province, covering coal, gas, oil, various types of fuel such as biomass; using alcohol fuel (e.g., methanol, ethanol, dimethyl ether, etc.), gas-fired boiler with reference to the implementation of emission limits.

After calculation, coal-fired thermal power boilers in Shaanxi Province implementation of the new standards, particulate matter, sulfur dioxide, nitrogen oxide emissions respectively about 0.67 tons 15,200 tons, 1.26 tons, down 27%, 40%, 21%; Burning after transformation of coal boiler, particulate matter, sulfur dioxide, nitrogen oxide emissions can be about 01,400 tons, 1.42 tons 14,100 tons.

With the haze pollution reduction work to promote strong, Shaanxi Province coal-fired generating units and 20 steam tons / hour or more coal-fired boiler to carry out the transformation of ultra-low emissions, will gradually iron and steel, cement and other industries to carry over non-electric low-emission transformation, the original standard has been overtaken by change of environmental situation. Additionally, the Guanzhong area of ​​glass, ceramics, bricks, gold and other industry, there are a certain number of kiln, its environmental requirements leniency.

The revision of the "off key industries in the region air pollutant emission standards", the abolition of the thermal power industry, coal-fired boiler emission limit requirements, these two sectors rose to individual standards province-wide.

It also increases the coke nitrogen oxide emission limits Chemical Industries, gold industry, glass and glass products, ceramic industry emission limits, increasing the concentration of tile industries and atmospheric pollutants conversion approach.

The new standards are expected coke chemical industry NOx emissions will decrease 70%, the sintering process the steel industry, the particulate matter, SO2, NOx emissions decreased by 50%, 72% and 67%, respectively.

At present 54.09% or 93918.38 MW of total electricity production in India is from Coal Based Thermal Power Station under coal fired CFB Boiler. A coal based thermal power plant converts the chemical energy of the coal into electrical energy. This is achieved by raising the steam in the CFB boilers, expanding it through the turbine and coupling the turbines to the generators which converts mechanical energy into electrical energy.

Xiao Bian tell you about the boiler combustion optimization control of those things: the boiler is an energy conversion device, in other aspects of power plant systems have been developed under perfect circumstances, boiler combustion system is a major part of energy-efficient coal-fired power stations and savings. Now, with the burner technology is improving daily, it has been able to adapt to all kinds of fuel combustion conditions and load, but the new requirements of energy saving power companies makes burning power plant boiler combustion stability not only meet, but also to meet the combustion process efficiency and reduce pollutants requirements emissions. It is necessary to further optimize the combustion process and operation. Today, we learn more about it. Generating hot water or steam boiler may directly provide the necessary heat for industrial production and the people's life, by a steam power plant can be converted into mechanical energy, or through the generator converts the mechanical energy to electrical energy. So, generally we use combustion expert system to monitor the implementation process, maintaining the boiler combustion efficiency and energy saving. Automatic water boilers, reaching full of water replenishment stops automatically, not manned, save time, save time, effort, labor. Increasingly comprehensive boiler combustion control means and the cumulative operating experience, providing adequate conditions for the implementation of expert systems. By burning power plant boiler combustion expert system of real-time status monitoring, by the mathematical model and expert system established by the corresponding combustion, can effectively adjust the boiler combustion, state correction due to various factors to the combustion process caused by deviation, to achieve optimal control of combustion. Structure designed according to the boiler pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic aspect. When using the boiler operation, hold down the control key forced to manually start and stop the boiler with water, the water level reaches very low safety level, the boiler automatically stops pay, the microcomputer controller after setting the boiler, the boiler began to work fully automatic, automatic replenishment, automatic heating, when the set temperature is reached, the boiler into the automatic insulation state. The coal boiler according to data analysis, secondary air damper temperature, and the load carried by the boiler combustion conditions, the coal and air flow control system to protect combustion boiler at its best, achieve fuel economy, reduce emissions of pollutants. The experience of the steel and building materials industries, the expert system can be achieved using combustion burn energy saving 2% -5%. You know what Btu boiler is not it?

Gas-fired boiler or electric boiler which is good?To compare the two kinds of boilers better, we need to understand the advantages and disadvantages of the boilers. The advantages of electric boiler are: 1, high thermal efficiency: can meet the requirements of winter heating in all regions; 2, electric boiler is beneficial to environmental protection: no leakage, low noise, no pollution; 3, convenient use: automatic control, no special guard; Intelligent thermostat automatic control, flexible and convenient use, indoor temperature can be set by their own needs, start and close the machine can be controlled by the computer. The disadvantages of electric boilers are: 1. The operation cost is high, is gas-fired boiler 2 times, is gas-fired boiler 4 times. 2. The boiler must be supplied with three-phase electricity at 380 volts. If there is a power loss or power outage, there is no alternative. Seriously affect the normal production and operation of enterprise units. The advantages of gas-fired boiler are as follows: (1) the thermal efficiency is as high as 90%: it can meet the requirements of hot water heating in all regions; 2. Gas-fired boilers are conducive to the national strategy of energy conservation and emission reduction, collect agricultural and forestry wastes such as straws that are directly burned and cause pollution, and produce gas granular fuels through processing, which can bring benefits to farmers. Greatly reduce emissions of pollutants from exhaust gases. 3, convenient use: full automatic control, no special guard; flexible and convenient use, 4, gas fuel is similar to coal gasification combustion and suspension combustion state, flue gas stays in the high temperature furnace for a long time, through the use of the gas fuel is similar to the coal gasification combustion and suspension combustion state. Multiple air distribution, anaerobic, upper feed, lower fire, lower suction combustion, full combustion, high fuel utilization rate, no black smoke. 5, using the furnace dust removal device, with which the original concentration of boiler dust emission is low, can not use chimneys. 6, continuous fuel combustion, stable operating conditions, do not be affected by the addition of fuel or stabbing, can ensure output. 7, the fuel source is extensive, the cost is low. Not limited by the season, can be used throughout the year. The gas-fired boiler is half of the gas-fired boiler, 1/3 of the oil-fired boiler and 1/4 of the electric boiler. 9. Fangkuai gas-fired boiler In a modular design, each system uses one furnace body, two combustion heads or two furnace heads, one burner head 300000 truck in summer, and two burner heads 600000 truck when heating in autumn. When the coldest in winter, you can open four burning stoves 80-1.8 million truck, that is, the heating boiler only uses 300000 calories in summer, 600000 calories in autumn, 1.8 million calories in winter, one machine multi-use. In this way, customers do not need to invest in two sets of equipment systems, greatly reducing their first investment costs and operating costs. The disadvantages of gas-fired boilers are: 1. Need free space or The warehouse is used for storing gas particle fuel; 2. Blower induced fan and other accessories need 220 volts, affected by power outages, but diesel engine can be used to power boiler accessories. Keep the boiler running as usual! Summary: gas-fired boilers and electric boilers are environment-friendly boilers, automatic control, can adapt to various areas, the price of raw materials is stable; but the operating costs of electric boilers are too high to be affordable by ordinary enterprise units. Too much reliance on electricity, once there is a power outage, will seriously affect the normal production and operation of enterprises. Gas-fired boiler is different, in all clean energy boilers, its comprehensive operation The lowest cost. Although electric drive boiler accessories are needed in ordinary operation, the dependence on electricity is not great, and diesel generator can be used to operate power driven boiler fittings in the state of blackout. Because gas particles fuel ignition point, is not flammable, so even if the stack in the aisle side also does not matter. Overall: gas-fired boiler is better, can save a lot of operating costs for enterprises, economic, practical and environmental protection, and its small shortcomings easy to solve the impact of little.
