boiler 68 ton and 10 ton

Looking back at 2018, we in the Group 'professional life, work lean, "the core values ​​of the correct leadership, and achieved fruitful results. "Fine positioning, precise process, continued optimization" is the connotation of professionalism we adhere to, in Group tireless efforts of all staff, we have made a number of break points to first academician workstation as the representative of the boiler 68 ton and 10 ton industry, which in the whole boiler industry are unprecedented achievement, for which we are very proud!

The use of superheater in boiler 68 ton and 10 ton

Most industrial boilers do not have superheaters because many industrial processes and living facilities require only saturated steam. In power stations, locomotives and marine boilers, in order to improve the cycle thermal efficiency of the entire steam power plant, a superheater is generally installed. Steam superheaters are widely used in steam boilers and waste heat-recovery steam boilers. Their purpose is to raise steam temperature from saturation conditions to the desired final temperature. When used in steam turbines, superheated steam decreases steam heat rate of the turbine and thus improves the turbine and overall plant power output and efficiency. Also, steam conditions at the steam turbine exit will have little or no moisture.

Gas-fired boiler 68 ton and 10 ton feed pump selection method! Water pump is the main equipment of gas-fired boiler, which is mainly used to replenish water of boiler to meet the normal water demand of boiler. The type selection of water pump mainly determines its flow rate and head. The specific introduction is as follows: 1, the flow calculation of feed pump: Q = k (Q1Q2): the flow rate of Q-boiler feed pump, m3 / h; Q1-Total water supply at maximum steam load for boilers, m3 / h; Q2-other water consumption, such as continuous discharge, periodic discharge and thermostat, m3 / h; k-standby factor 1. 1 ~ 1. 2.2, calculation of feed pump head of gas-fired boiler: h = H _ 1 H _ 2H _ 3H _ 4: h-boiler feed pump head, m; H _ 1-boiler opening pressure of safety valve under designed pressure, MPa; Resistance of H _ 2-economizer and water supply pipeline system, MPa; H _ 3-difference between the highest and lowest water levels of the water supply system, MPa; H _ 4 & mdash The other. 3, the gas-fired steam boiler feed pump shall be provided with a reserve, and when the maximum feed pump stops operating, the remaining total flow rate shall be able to meet 110% of the water supply required by all operating boilers at the rated evaporation capacity; When the boiler room is equipped with a dewarming device or a heat accumulator, the total flow rate of the feed pump shall be included in its water consumption. 4. One or more boilers with the same steam pressure may choose to operate side by side with two or more feedwater pumps, if the main pipe is used for water supply, Then you can choose two pumps and one backup, then frequency conversion water supply, which not only reduces the consumption of electric energy, but also makes the water supply pressure stable, although the one-time investment is relatively large. However, by means of frequency conversion and energy saving measures, the investment cost can be recovered in 3 years and 4 years. 5. Gas-fired steam boilers use steam-driven feedwater pumps as accident backup pumps. Its flow rate should be able to meet 20% ~ 40% of the water supply required by all operating boilers at rated evaporative capacity. Only when the boiler room with the first-class electric load and the feed pump stop running will not cause the boiler to be short of water, the steam-driven feed water pump may not be installed, and the non-power boiler room of the general industrial enterprise does not have such conditions, so it must be set up. Boiler selection has a direct impact on the boiler water supply system, it should be carefully selected.

Gas-fired steam boiler 68 ton and 10 ton and gas consumption life-related factors: the gas boiler steam boiler this kind, I believe we will not feel strange, but, for us it is also possible to broaden their knowledge, and then to increase their amount of knowledge in this area. So, now that is good for us, then, what reason not to be taken seriously and be it! So as not to let themselves more harm than good. 1. The thermal efficiency of gas steam boiler, what should I look at, it is more and is and correct? Thermal efficiency of gas steam boiler, which in general, on domestic and imported brands is somewhat different, but, imported brands is higher. Note, however, that on some parameters and the boiler, which is in the specific range, there are some provisions, mainly to see if it is a certain percentage of the thermal efficiency of the boiler operation. 2. Gas-fired steam boiler, which is on the nameplate, whether there is life in it? Gas-fired steam boiler, which is on the nameplate, which is not described in this life, so, on this issue, that the answer is no. But in general, it scrapped its standard, and is in a period of less than thermal efficiency requirements, or can not ensure the safe operation and use of the boiler, then, is a must to be disposed of.
