Gas should be properly filtered, gas-liquid separated and stabilized before use. If the temperature is too high, it should also be cooled to ensure that there is no liquid component in the gas. The pressure change rate is less than 1 kPa/min, the tar content is less than 50 mg/Nm3, the impurity size is less than 5 micron, the moisture content is less than 20 mg/Nm3, and the impurity content is less than 30 mg/Nm3. Calorific value is greater than 800 calories.
Safety of Coking Gas Generator Unit
In terms of unit safety protection, dry fire arrester and emergency cut-off solenoid valve are installed on the intake pipeline. In addition, explosion-proof doors are installed at both ends of the intake pipe to ensure the safe operation of the unit.
Technical Characteristics of Coking Gas Generator Unit
At present, the generators in the domestic market are all high-speed engines, which is not conducive to the mixed combustion of combustible gases. In practical application, 300 series gas engines have obvious advantages compared with similar domestic products.
A. It can output high and medium voltage to reduce initial investment and operation cost.
The gas-fired generating units produced by our company can customize 10500V, 6300V, 400V high, medium and low-voltage output to meet the different needs of users, avoid the initial investment of purchasing transformers, reduce copper losses and operation costs, and can be connected to the grid and used directly with load, thus greatly improving the economic and social benefits of the units. Benefit.
B. Large Cylinder Diameter Guarantees Continuous and Constant Output Power of Unit
The original engine of the gas-fired generating unit produced by our company is a modified 8300 diesel engine with a diameter of 300 mm. It has the advantages of large diameter, long stroke, low speed and large power reserve. It is more suitable for the characteristics of low gas pressure than the high-speed generating unit. It is the best prime mover of the gas-fired generating unit and ensures the constant output power of the unit.
C. Low Speed to Ensure Service Life of Unit
The original speed of Zichai gas-fired generator set is 500 r/min or 600 r/min. Low speed can reduce engine wear and tear, prolong the service life of engine parts, reduce spare parts reserve and improve the economic benefits of users. For example: low speed, low requirement for the matching clearance between the shaft and bearing bush, small wear of the shaft and bearing bush, and less scratching. Low speed, low frequency of valve movement, less wear and tear of valve and valve seat, plus valve and valve seat made of Zichai special material, more than a year of operation, no need to replace. The high-speed unit runs for an average of about 3000 hours, requiring replacement of valves and valve seats once.
