good quality gas steam boiler corrugated furnace

At 15:31 on January afternoon 55 points, Zhangjiakou Municipal Publicity Department announced through the official micro-Bo: Zhangjiakou Shiqiao Eastern red floor Combibloc bath center for illegal use of obsolete coal-fired boilers, boiler and furnace door ring gall bladder junction cracking, resulting in rapid ejection soda.

At present, the accident has killed two people were killed and two injured, the injured have been rushed to hospital.

Since the accident the suspect, the suspect has been controlled.

It was a painful stricken by the accident, the suspect illegal use of coal-fired boilers have been eliminated, resulting in four families forever pain.

As can be seen from the government over the country began to strictly limit the use of coal-fired boilers, coal-fired boilers in order to face a fate or modification or elimination of the unlawful use of coal-fired boilers have been eliminated but can cause great harm, the accident is a obvious example.

Therefore, actively cooperate with the investigation of the relevant units of boilers, boiler out of strict compliance with the Code and running, grasp the safe operation of the boiler to a large extent, reduce the occurrence of such tragic accidents.

Fire boiler design pitch is much: a room, boiler production plant belongs to class D, to a good quality steam boiler corrugated furnace rated evaporation 4t / h, when the rated output is greater than 2.8MW hot water boiler, the boiler room building fire resistance rating of not less than two ; rated evaporation steam boiler is less than or equal to 4t / h, when the hot water boiler is equal to or less than the rated output 2.8MW, between the boiler building fire resistance rating of not less than three; m-inter-tank, oil pump and the oil heater are inter production plant belonging to class C, not less than two of its construction fire rating, between said room is arranged within the auxiliary boiler room, a room should be set apart from other firewall; March and gas regulator production plant belonging to Group A, which building fire rating of not less than two, should be provided between the boiler room and the immediate neighborhood regulator firewall spaced boiler room, which doors should open outwards and should not directly access to the boiler room, the ground should not be spark Ping.

Different natural gas good quality steam boiler corrugated furnace energy-saving measures as well as gas-fired boiler with environmental issues become more critical, more and more people are concerned about the importance of the environment for our development. Today, gas steam boilers in industrial production is very common, how to reduce the energy consumption of gas steam boilers, which we have been explored. We can take the following measures in natural gas steam boiler operation for energy. 1, the amount of steam needed for industrial production of a reasonable choice, and the number of the rated power station boiler steam boiler gas, in both cases the higher the degree of matching with the actual exhaust gas loss is smaller, the obvious energy saving. 2, the fuel in contact with air: fuel amount so that an appropriate amount of air and the optimum composition ratio of combustion, this would both improve fuel combustion efficiency and reducing emissions of polluting gases, energy to achieve the dual goals. 3, reducing the temperature of the exhaust gas steam boiler: the temperature of the boiler flue gas to reduce the effective use of exhaust heat generated in general, the efficiency of the boiler used is 85-88%, the exhaust gas temperature is 220-230 ℃. If the setting of energy-using the exhaust heat or the like, the exhaust gas temperature falls to 140-150 deg.] C, the boiler efficiency can be increased to 90-93%. 4, recycle heat from the boiler blowdown water: water using continuous blowdown heat by heat exchange, in addition to improving water temperature itching water to achieve energy saving gas steam boiler. At the same time, measures energy-saving gas steam boiler can also be reasonably recovered condensate heating system, and the heat of the condensate water recycling. It is different from the gas boiler and gas boiler: 1. Gas circulating fluidized bed combustion boiler coal by crushing device by the belt into the coal bin, by using multicast coal stoker wind, thrown into the furnace; circulating ash by heating, fluidized combustion process. After coal to gas and coke oven gas and purge gas mixed together by the four burners directly injected into the combustor. 2. Combustion of Coal is mainly composed of water and ash content and the elements C, H, O, N, S etc., the heat released by combustion of coal to produce SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx discharged from the flue gas the atmosphere, pollute the environment, cause harm to humans. And the main component of coke oven gas and purge gas are CO and H2, after combustion, produce mainly CO2 and H2O, SO2 emissions relative gas boiler gas boiler, SO3, NOx is much less. 3. Usually ventilation negative pressure combustion gas boiler, the combustion process is to group together to complete the mating with the mating blower and induced draft fan, the coal combustion process, requires a lot of air and the furnace wall due to the leakage of the flue, the excess air coefficient of up to between 2.1-2.5. Gas boiler combustion slightly positive or slightly negative pressure, a small amount of wind required, air is preferably premixed with the gas within the combustor. No leakage factor positive pressure combustion flue and the furnace wall, the flue outlet air ratio operation may 1.05-1.2.4. Fuel explosive gas boiler combustion safety, the furnace explosion hazard unlikely to occur. The gas-fired boiler in the explosive concentration limits encountered fire will explode. More dangerous. 5. Gas boiler control difficult due to coal boiler, material thickness, amount of the blowing, the amount of the wind, the wind mixture ratio of coal and other reasons, to be automatically adjusted according to the operating parameters of the boiler load is large. Less impact on the factors of the gas boiler, the burner may be adjusted according to the size of the load valve, easy to achieve automatic control.

35 tph SZS gas-fired water tube boiler project for dairy industryPlenty of steam is needed in the milk powder production process of sterilizing, concentrating and drying; therefore, a stable good quality steam boiler corrugated furnace has a direct impact on the milk production quality. Heilongjiang Feihe Dairy Industry Co., LTD., established in 1962, has won the Gold Award of Monde Selection. As hazy weather appears frequently in recent years, air quality issues have aroused great concern of the whole society. The Chinese government has successively launched "coal to gas" and other environmental policies to improve the air environment. Feihe Dairy is taking an active part in environmental protection, the company decided to replace the present 2 sets of 35 tph coal-fired steam boilers and one set of 20 tph coal-fired boiler with 3 sets of 35 tph gas-fired steam boilers. Considering that the steam boiler is a core equipment of the production line, the company had attached great importance to this purchase and held an open tender. ZOZEN successfully won the bid with excellent product quality and service, and provided the company with 3 sets of SZS series gas-fired steam boilers. This series of boiler adopts the design of membrane water wall; the gastight test must be done before installing thermal insulation layers, to ensure there is no flue gas leak under the condition of micro-positive pressure combustion and help reduce the heat loss of the boiler body. In addition, to effectively reduce the NOx emission, the boilers are equipped with large volume furnaces and advanced low NOx burners imported from Europe.
