Such as boiler load increased, but also to ensure the boiler load unchanged or decreased in order to prevent pressure shall increase the amount of fuel and air supply, strengthen the burning, causing the furnace exit flue gas temperature of the flue gas volume increases and lower water temperature , temperature increase; If the oil and gas fuel is combusted in the furnace carbon black is not fully formed, into the superheater flue causing secondary combustion, but also greatly increase the superheat temperature. Reducing the temperature of the main reasons: improper adjustment of combustion, low flame center furnace; superheater area is small, or too much leakage at the furnace wall; Save water flow rising or temperature reduction; drum water level or high gas-water separator separating efficiency is lowered, the humidity of the vapor is increased; superheater tube fouling, reduced heat absorption and the like.

To introduce steam boiler pressure gauge and hydraulic press accumulator using steam boiler pressure gauge should pay attention to: 1, rated steam pressure is less than 2.45MPa steam boiler, the accuracy of pressure gauge must not be 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The diameter of the dial of the pressure gauge shall not be less than 100 mm to ensure that the operator can see clearly the surface pressure indicator value. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. Steam boiler pressure gauges should be installed in a place that is easy to observe and wash. 4. Steam boiler pressure gauges should be checked at least once every six months, and should be sealed with lead after calibration. 5. Steam boiler pressure gauges should not have leakage of water and steam leakage in the connecting tubes of the pressure gauges of steam boilers. (4) the steam boiler pressure gauges should be checked at least once every six months and sealed with lead. 5. Otherwise, the pressure indicator value will be reduced. 6. The measurement range of the steam boiler pressure gauge should be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have pressure gauge, the pressure gauge is damaged or the installation of pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following conditions: 1, broken surface glass or dial calibration mold There is no clear paste; 2, no lead seal, lead seal damage or beyond the calibration period; 3, without pressure, the pressure gauge of the finite pin can not be restored to the limit pin, the infinite position of the gauge pointer deviated from zero data beyond the allowable pressure clothing; 4, gas leakage or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge. Purpose of the accumulator: the accumulator is used in the hydraulic system of intermittent machinery, which stores the oil output of the hydraulic pump during intermittent or low-speed movement of the actuator, and when the rapid movement of the actuator requires a large flow rate, As an auxiliary energy source, together with the hydraulic pump, the oil pump is supplied to the system, thus the oil pump and the hydraulic pump are realized. The miniaturization of the whole hydraulic device absorbs the quick opening and closing of the impact hydraulic reversing valve and the sudden change of the load. The system will produce shock pressure, the darling will lead to vibration and noise, and even damage the machine. The accumulator can mitigate the impact pressure absorption pulsation of these fluids absorb and reduce the flow pulsation and pressure pulsation of various hydraulic pumps thus reducing the system noise and vibration. The damped accumulator acts as a gas spring and can be used to absorb the vibration between the fuselage and wheels of walking machinery such as vehicles. The balanced accumulator absorbs the gravitational potential energy of the vertical actuator (hydraulic cylinder) and its load as it falls. When the vertical actuator rises, the accumulator releases the original absorbed energy and supplies oil to the hydraulic cylinder together with the pump, thus realizing the balance and energy saving.

The oil in the gas-fired boiler, it carries on the classification according to the partition, has what kind? How to avoid the problem of ash accumulation in boiler superheater? And, with regard to boiler this important website product, what other questions need to be explained and answered? The main purpose of raising these questions is to solve them thoroughly so that we can understand them clearly and have a correct understanding.

01. What are the specific types of oil in a gas-fired boiler, if it is classified according to its formula? If oil in gas-fired boilers is classified by formula, then it can be divided into two categories: alcohol-based and petroleum-based. Moreover, alcohols are usually composed of methanol, or ethanol, and other high-carbon alcohols, while petroleum is a mixture of various waste oils and light oils, with a calorific value higher than that of alcohols. 2. How to avoid ash accumulation of boiler superheater? In order to avoid ash accumulation in boiler superheater, attention should be paid to the rationality of flue structure and the correct flow direction of flue gas when passing through the superheater. In addition, soot blowing can be carried out frequently, so that this problem can be avoided, and at the same time, ensure that the boiler can work smoothly and normally. 3. Lighting requirements for water and pressure gauges in gas-fired boilers and contents of boiler nameplates

Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.

Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program" (hereinafter referred to as the "Program") said that before the end of 2018, the province's 300,000 kilowatts or more coal-fired units completed ultra-low emissions transformation. Continue to promote the 200,000 kilowatts class ultra low emission coal-fired unit renovation project, before the end of 2019, ultra-low emissions and strive to transform the province's total unit capacity of thermal power capacity of more than 75%.

"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.

In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.

In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.
