Water Tube Double Drum Boiler

Gas Fired Hot Water Boiler H6

Business issues to be considered in the selection water tube double drum boiler summarized as follows: 1, the enterprise itself how much heat for steam and hot water needs heating or heating in the production process. 2, steam boilers or hot water parameter parameter. 3, analysis of the relationship between steam boiler and hot water boiler selection. 4. Select the boiler furnace industry. 5, a coal burning boiler. 6, other dimensions, such as load changes. 1, how to determine the capacity and the number of boilers: how to determine when to buy boiler boiler capacity is an important issue. In general should be determined according to the boiler output or capacity of the production process or heating steam consumption and living area with heat for hot water needs. First, the user wants to find out the total load range; peak followed, including the duration of the peak load, peak frequency, which is cyclical peaks occur, for example, the peak number of occurrences per month, week, month and year in winter and summer differences. Find out the peak and the total load need be considered after the device capacity and the number of units selected. Should also be considered when selecting the amount of spare accident shutdown problem. Generally it refers to an amount of a standby spare boiler. It needs to be determined based on the user's own importance, if the production and use on the higher continuity requirements must seriously consider the issue of spare equipment.

Gas water tube double drum boiler energy-saving technology to explore because of China's natural gas prices are relatively high, so when using a gas boiler, how to save the cost of one of the problems is the business focus. Note that in addition to the use of natural gas boilers use a method other than the thermal efficiency of the boiler itself is an important criterion for the energy efficiency of the boiler, today to talk about these issues which are under the technical energy efficiency gas-fired boiler. A reduced heat losses measures analysis of heat losses mainly by the exhaust gas temperature and excess air ratio α of impact, wherein the excess air coefficient α is too large, causes an increase in the amount of flue gas, more heat away, it should be decrease in efficiency of the boiler is provided to ensure that the combustion air ratio as much as possible, by properly configuring the burner, strict debugging operation, its structure and the characteristics of the boiler, the type and characteristics of the fuel matched to ensure flame furnace filled with the fuel combustion. Select the burner has a proportional regulating function, varies heating load can be automatically adjust the ratio of air to gas supply and the gas in the boiler load range, while always maintaining high combustion efficiency, to ensure a reasonable excess air system, to reduce heat losses to improve the thermal efficiency of the boiler. Since the heat loss, the heat loss of water vapor carried by 55% to 75% of the heat losses, if the flue gas flue gas temperature drops below the dew point of water vapor by recycling latent heat, can be effectively reduced smoke and heat loss and improve the thermal efficiency of the boiler. For this reason, a low temperature heat sink to be taken to achieve the effect of condensation and heat recovery. A low temperature heat sink from the structure can be divided into two kinds of integral and separate. Is the integral of said general condensing boiler, heat recovery is to install separate outside in a conventional boiler flue. Second, the condensing boiler is a condensing boiler means of latent heat of vaporization of water vapor contained in the boiler can be absorbed from the flue gas in the boiler exhaust. The most conventional boiler flue gas sensible heat transferred to the water or steam, and condensing boiler will not only sensible heat transfer part of a larger feedwater or steam, but also absorbs the latent heat of vaporization of water vapor in the condensing part of the fumes released. Condensing boilers and conventional boilers in design thinking is very different. Condensing boiler condensing heat exchanger must have a heating surface, high-performance insulation housing and the sealing material. A low temperature water temperature of the boiler flue gas flue gas condensation temperature drops, the state of the flue gas in the form of superheated steam condenses into water, releasing latent heat of vaporization, this part is still used for the heat recovery boiler. The fuel is calculated based on net calorific overall efficiency than conventional shell boiler as much as 10% to 17%. Exhaust gas temperature can be reduced to 50 ℃ ~ 70 ℃. Condensing boiler not only saves energy, but also water vapor in the flue gas is condensed, while the flue gas can be removed harmful substances, and a considerable amount of water recycled with energy, water, and environmentally friendly. Condensing boilers in foreign applications are quite widespread. Third, the installation of a conventional waste heat recovery boiler flue gas heat recovery unit separation can generally be divided into direct and indirect contact with heat exchanger. Direct contact heat exchanger using water spray in direct contact with the flue gas for heat and mass transfer. This way high heat recovery rate while absorbing a large amount of harmful substances in the flue gas, however, in this embodiment the recovered acidic water quality, limited use, hot water generated in waste heat recovery in general is difficult to use civil heating boiler room, thus heating boiler room is generally not used in this way. An indirect heat exchanger, also known as flue gas condensation heat recovery. Flue gas boiler because the water vapor content of more water vapor in the flue gas large latent heat of vaporization released during condensation, so that the gas condensing boiler employed heat recovery device effects than traditional coal-fired boilers used economizer higher efficiency, installed on a conventional flue gas waste heat recovery boiler flue, can improve the thermal efficiency of the boiler, reducing the waste of energy, but also can reduce the operating costs.

How to determine the level of small gas steam water tube double drum boiler in severe cases, to carry a large amount of water steam, increasing the salinity of small gas steam boiler, water hammer occurs sound steam pipe, the steam from the connection flange drop out; when the water supply It is less than the flow rate of steam flow, or if due economizer tube rupture caused by lack of water, the opposite phenomenon occurs. When the severe water shortage, from the door you can see the red water wall tube, you can also smell the coke. Meanwhile, the tube may crack, this time can be heard the blast, and the vapor and flue gases discharged from the door, fire doors look. Small gas steam boiler when the water level is below a predetermined value, the fan motor should be stopped, the induced draft fan and grate speed reducer, the security level is lower than the low water level, the water level gauge glass (plate) as a white. Rinse water level gauge to determine the small gas steam boiler is full of water and mild or severe full of water. Method: Turn off water level, water plug, then open the drain plug, if they can see the water level from top to bottom, indicating that it is a little full of water, open sewage valve, into the normal water level. If the water is full of serious, due to take urgent measures to stop work.
