Contrast gas steam china industrial fired boiler and gas steam boiler? Which is more cost-effective? There are new users will ask gas steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear leadership and gas steam boiler, gas steam boiler supporting a dedicated burner, a burner just put the cost price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than gas steam boiler more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. In which the gas steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Gas-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that now more stringent gas steam boiler. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze fuel costs: gas steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view than the gas steam boiler Gas steam boiler in order to save more on operating costs, but gas steam boiler environmental protection, now increased pollution than gas steam boiler in environmental protection in recent years so the state more stringent control of environmental pollution, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.
Hebei province is the use of industrial china industrial fired boilers, countless large and small boilers, air pollution caused by coal-fired boiler is one of the problems of governance in Hebei Province, and therefore become a major coal-fired boiler control of air pollution in Hebei Province direction. Coal-fired auxiliary boiler control work steadily, the Hebei provincial government to develop a "" comprehensive management of air pollution in Hebei provincial financial assistance fund management approach ", the boiler subsidy detailed as follows:
1, rural areas electricity instead of coal subsidies
The household equipment purchase and install (including line transformation indoor) 85% of investment subsidies, the maximum subsidy per household amount not more than 7400 yuan, the provincial and city and county respectively 50%, the rest borne by the users themselves.
Residents give electricity for heating 0.2 yuan / kwh subsidies, provincial, city and county average bear, the highest household electricity 10,000 kwh subsidies, subsidies and standards tentatively scheduled for three years.
2, substitution of gas for coal in rural areas subsidy standards
The household gas equipment purchase and install the 70% investment subsidies, the maximum subsidy per household amount not more than 2700 yuan. Provincial cities and counties and respectively 50%, the rest borne by the user.
Heating gas for customers who use 1 yuan / cubic meter of subsidy per household per year up to 1200 m3 gas subsidies, provincial, city and county average bear, subsidies and standards tentative three years.
Given the highest building in the village of pipelines family home investment subsidies of 4,000 yuan, 1000 yuan assume the provincial, city and county to bear 3,000.
3, coal-fired boiler subsidy governance standards
Subsidies for coal-fired boilers, eliminate subsidies, a separate ban demolition of 30,000 yuan / tons of steam, the implementation of clean energy transformation of 80,000 yuan / tons of steam.
4, thermal power shutting down out of subsidies
Provincial for shutting down the unit by 300 yuan / kilowatt award given up, have been included in the national "Thirteen Five." Plan for shutting down the unit, illegal construction unit, run-of-life choice except unit and power capacity index trading.
Because of the particularity of the oil-gas china industrial fired boiler, from the initial construction preparation to the long-term acceptance of the project, there will be some problems to be paid attention to, and what should be complied with? Boilers need to follow the steps step by step to complete. What needs to be observed in the process? Oil and gas dual-use boiler installation before construction, first in accordance with the rules to first handle the boiler installation approval formalities, pending quality and technical supervision bureau approval after! Safety valve is an indispensable safety protection device in industrial boiler. Lever type safety valve can be often used, it can be divided into two types: single lever and double lever. Well, it was run in an industrial boiler. How does the lever-type safety valve work in the process? Why to carry out the air pressure test on the boiler? The lever type safety valve in industrial boiler is basically composed of valve core, seat and important lever, weight hammer and position limiting device. It acts on the valve core through the heavy torque of lever and weight hammer to flatten the pressure of steam. The main energy consumed in the operation of oil-fired boiler becomes fuel oil, so the quality of fuel oil will be directly related to the whole combustion state of the boiler, so how to choose fuel oil to supply to the oil-fired boiler? Generally divided into light fuel oil and heavy fuel oil two major categories. Fuel-fired boilers burn differentiated fuel oil The composition of the oil supply system will be different because of the different characteristics of the oil.
Steam china industrial fired boiler pressure gauge should pay attention to matters 1, rated steam pressure less than 2.45MPa steam boiler and pressure gauge accuracy not only in 2.5; rated pressure steam boiler child or equal to 2.45MPa, the pressure is too spread made not less than 1.5 level. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, working pressure, typically 1.5; 3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.
