Another technology being incorporated by boiler manufacturers is the gas turbine.When a gas turbine is used, natural gas is fired, and the hot gasses are used to spin a turbine attached to an electrical generator to make electricity.Since there is still available heat in the gas that exhausts from the turbine, it is then sent through a Utility Power HRSG (Heat Recovery Steam Generator).Similar to a watertube boiler, the hot exhaust gasses from the turbine heat water in the tubes of the utility power HRSG and turn it into steam, which is then used to turn a second steam-driven turbine attached to another electrical generator.This technology is called “Combined Cycle Cogeneration”, and is a very efficient use of fuel because the same fuel source is used twice to drive turbines.

We found that there are a lot of people on both boilers and vertical 3000kg steam generators could not tell, and take a lot of detours at the time of counsel and buying. Through the above comparison of the differences we boiler and steam generator, it can first in accordance with the needs of their business, and then determine the selection Which devices.

In response to the call of the State Environmental Protection Department, to further improve air quality, enhance people's happiness blue sky, located in Leshan City, Sichuan Province of the energy restructuring and clean coal-fired boiler as the primary task of air pollution control, to promote the elimination of coal-fired boilers remediation work. According to statistics, from January to October this year, Leshan City, the main urban air quality index improved 11.86 percent year on year, a figure that ranked third in the province; a few good days of 251 days, an increase of 29 days, compliance rate of 82.57%; PM2.5 average concentration of 44.5 micrograms / cubic meter, an improvement of 14.09%; PM10 average concentration of 69.0 micrograms / cubic meter, an improvement of 5.74%. Improve these figures can not be separated Leshan Municipal People's Government's strong support and initiatives. Leshan municipal government adhere to precise planning, but also a public green, clean living environment.

A careful planning. Since 2017, vigorously promote energy restructuring and transformation of coal-fired boilers, in-depth investigation status of the city's coal-fired boilers, having accurate number of the city's coal-fired boilers, steam tonnage and treatment facilities, the establishment of coal-fired boilers ledger. To promote the implementation of the "coal to electricity", "coal to gas" projects the city's key industries, coal-fired boilers to transform, adjust the expansion of high-pollution fuel combustion zone ban.

Second, the fine classification. Classification of coal-fired boilers to carry out renovation work, from the source strict control of new coal-fired boiler, new and expansion projects to encourage the use of electricity, natural gas and other clean energy; with the implementation of small coal-fired boilers eliminated, medium and large transformation. The city 10 steam tons / hour or less and a total of 717 small coal-fired boiler units are all clear, a total of 1030 tons of steam. Medium-sized coal-fired boiler clean energy transformation or transformation in accordance with the deadline for ultra-low emission "should gas is gas, should the electric power" principle, Taiwan is currently the city's 44 large and medium sized coal-fired boiler clean energy transformation has been completed and ultra-low emissions transformation.

Third, the precise advance. Strengthening full control of behind schedule inspectors to speed up reform. Strengthen financial subsidies, to boost the progress of work, more than 7 million arrange special funds for the transformation of the atmosphere and medium-sized coal-fired boiler subsidy, cities, counties (cities, districts) to finance 20 steam tons / hour and clean energy alternative to coal-fired boilers the implementation of special subsidies.

Small gas steam boiler in the hotel building applications in daily production, how to save energy and reduce the emission of pollutants, reduce costs, increase economic benefits to the business, the real problem is getting attention, and gradually resolved. Shenyang is a hotel accommodation, offices, restaurants, stores in one large commercial buildings, construction area of ​​6 × 104m2. During the heating period, heating systems, domestic hot water steam system, laundry room used by the municipal heat supply network. After the heating period, domestic hot water systems, steam laundry prepared from 2 model white WNS8-1.25-YQ fuel steam boiler (heating of serving as backup boilers) for the steam, steam production of single 8t / h. Steam boiler room to the sub-cylinder (in the basement podium) linear distance is 200m, and specifications for the steam supply pipe DN250mm, Buried employed, the compensator 4 disposed manhole. Based on the actual measured amount of steam on the hotel, and the application of energy-saving small gas steam boiler in the hotel building were discussed. Selection 2 gas steam boiler us 2009 June 7 to July 1 for steam consumption for domestic hot water systems, laundry room were measured. Average pressure of 0.08MPa steam, hot water systems, laundry average daily amount of steam were 7.43,2.43t / d. Two systems together, the maximum amount of steam per unit time and the average amounts were 0.77,0.41t / h. From the measured data, daily 9: 30-11: 30, 15: 30-17: 00 cooking gas peak, the highest air consumption is 19.65m3 / h, the hotel into the household gas pipeline gas supply capacity of 95m3 / h. According to domestic hot water, laundry room two systems unit time summer highest steam consumption is 0.77t / h, should be used in a 1t / h gas steam boiler, its gas consumption is 76m3 / h. In actual use, reasonable arrangements for gas time, can fully meet the demand for gas gas steam boiler. From the above analysis, the steam production of the hotel is much larger than the existing fuel steam boiler steam summer practical usage. According to the measured summer daily expenditure of more than just fuel costs more than 3000 yuan / d. Underground layer may be mounted on a podium 1t / h gas steam boiler, steam lines since all indoors, and therefore low cost pipeline system, and reduce the emission of pollutants, environmental protection efficiency significantly. 3 gas steam boiler room design of the hotel podium underground over 3 floors, including the basement of the original generator set oil storage has been discontinued, construction area of ​​about 60m2, close to the basement exit ramps from the gas pipeline into the family 8m, after transformation, can be used as gas heating boiler room. Gas heating boiler heating system flow shown in Figure 1. Gas heating boiler to be mounted ventilation system, the ventilation normally not less than 6 times / h, accident ventilation of not less than 12 times / h, the amount of exhaust air volume should be slightly larger, so that the boiler room space maintain positive pressure, and the ventilation should be selected proof products. Gas heating boiler to be mounted combustible gas detection and alarm devices, combustible gas detection and alarm device to automatically signal when gas leakage occurs, the emergency shut-off valve closed and to ensure that no further leakage of the combustible gas. Water spray system shall be installed, and the sprinkler system in conjunction with the original. Gas heating boiler in order to prevent water from leaking into the premises are ground floor, the ground should boiler room waterproofing and drainage ditch, the concentrated water discharged to the ground floor drainage system pressure, into the room promptly [1,2 ].
