2010 kg gas steam generator

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 ].

Eliminating the problem of pressure test: GB150-1998 "Steel Pressure Vessel" Article 3.9 states: "to not make container pressure testing in accordance with the provisions of 3.8, the design unit should put forward measures to ensure the safe operation of the vessel, and note on drawings Ming "There are many standard deviations the user's understanding of this provision, is summarized in the need to clarify the following two questions: First, under what circumstances can relieve stress test? Second, the measures may be required after relieve the pressure test? When the catalytic cracking unit with a regenerator and a large reactor and the heat insulating layer can not withstand those based hydraulic test: in fact, only relieve pressure test performed Spot welding large pressure vessels for pressure testing the impossible, such as water by weight of the pressure vessel and the like. In other words, the reason why the pressure test exemption, because they do not have the container or a pressure test, or simply not pressure tested. In short, rather than eliminating means you can not do not do it, it is not without basis as a general pressure test in the factory production of pressure vessels. It should be noted that the pressure here means a pressure test test.

The basic configuration of the heat of the gas steam boiler steam boiler and service method is natural gas, liquefied petroleum gas, fuel gas such as city gas as fuel, the combustion in the furnace released heated pot water, and allowed to vaporize into steam heat conversion equipment. Water in the pot is continuously released from the combustion of a gaseous fuel energy to heat the furnace, raising the temperature and generating steam under pressure, since the boiling point of water with elevated pressure is raised, the pot is sealed, the expansion of the water vapor inside limited dynamic pressure generated heat is formed as an energy source is widely used. Steam boiler fuel burn-up and to ensure that the flue gas outlet temperature was cooled to a safe value convection heating surface of the work; using the heat of the flue boiler feedwater heating, in order to reduce exhaust gas temperature, fuel economy and functions. Each 2010 kg steam generator heating surface and joined together and water wall tubes and other components decreased water circulation circuit. Soda storage drum, can adapt to changes in load, with internal steam separator means to ensure the quality of soft drinks, no DC boiler drum. Gas steam boiler feed water must go through qualifying process, which is to extend the life of the boiler, ensure the safe operation of the important issues. Water temperature should be close to the furnace temperature. Must regularly inspect the low water cutoff maintenance and cleaning. Water Level Controller cleaned at least once a month, rinse water table at least once a day. Rinse water table should be at the highest level; after flushing the water level should not be less than the minimum safe level, not as a net wash, can wash many times, but it must be flushed at the highest level. Require periodic sewage operation, at least once a day, after the sewage drain valve should be checked because of possible contamination and leaks; if it must be excluded. When shutdown is not maintained while the steam pressure, the steam space of the boiler will produce negative pressure air entrapment, and therefore should rise again to the fire burning total steam valve is opened.

There are a few big happy event in life, conclude, than the following: drought every winter rains, foreign land refresher, the wedding night, pass the examination, as well as being hit Awards. In March this year, planned by the fast Boiler Group hosted the second session of the boiler room] [best photo contest Huobian country! Fans actively participate in activities perfect ending. Gain a lot of excellent photographs, the Group established a review panel for the competition each photo a rigorous review, and ultimately selected a first prize, two second prize, third prize 3. In addition, the panel of judges based on the results of online voting to elect Choice Award six.
