Pressure boiler furnace designed to fully consider the characteristics of the fuel pressure boilers body member are two main drum and furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. The overall structure of pressure boilers and boiler auxiliary equipment including two parts. Boiler furnace, drum, burner, water wall superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Furnace design needs to fully consider the characteristics of the fuel used. Each boiler should be fueled with the original design of the fuel. Boilers running economy and reliability are likely to vary greatly reduced when using the characteristics of fuel combustion. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler.
Henan newly installed gas boiler 1 what kind of work before starting. Henan newly installed gas boiler before starting what should be done? These include: the tightness of (1) hydrostatic test (overpressure test), test pressure member. (2) Trial and various auxiliary electric door damper check. (3) oven. Water inside wall of the furnace and gas water boiler tubes Henan removed. (4) cooking stove and pickling. Remove grease deposits in the evaporator heating surface system, rust, oxide scale and corrosion products, and other like with lye and acid. (5) furnace aerodynamic field test. (6) flushing pipe. Henan boiler with gas flushing a self-generated steam, the second steam duct heteroaryl residue. (7) check security doors. 2. Henan gas boiler before start time and temperature of water on what regulations? why? Water speed before the start of Henan gas boiler should not be excessive, winter generally less than 4h, other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Cold boiler water temperature is generally not more than 100 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Henan not completely cooled gas boiler drum water temperature, mutatis mutandis, wall temperatures, generally the difference should be controlled within 40 ℃, it should slow down or speed water. The reasons are: (1) Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. If the inlet water temperature is too high or too fast, uneven expansion will cause the weld cracks occur, resulting in damage to the equipment. (2) when the water supply enters the drum, the drum is always in contact with the first half wall, if the water temperature and the drum wall temperature difference is too large, the influent fast speed, on the drum, the lower wall, the inner and outer wall inter will have a greater expansion difference, caused a large drum to additional stress, causing deformation of the drum, when severe cracks.
More details gas boilers should be promptly after use as a steam boiler manufacturer for foam factory plant drainage, heating, bath with gas boiler is a kind of fuel for the gas equipment (fuel gas-fired boilers), because it is compared with oil-fired boiler, electric boiler up more economical, which is widely used. After carrying out the gas boiler must turn on the water to be disabled. Why is that? We will come and detailed discussion about this issue today. To turn on the water when the gas boiler is disabled: gas boiler in the boiler water if the winter will put the cracking, there will be odor and summer long embroidered, so that the life of the boiler will be reduced. At the bottom of the boiler there is a turn on the water with the section of the door, then opened, gas boiler pipes in the water will flow back to the boiler, the boiler is done and the water on it. Water level controller SZB-IV (electrode type water level alarm) 1. When the normal level of + 30mm, pump control switch contacts are open, the pump stops working. 2. When the normal water level -30mm, pump control switch contacts in contact, the pump starts to work. 3. When the normal water level of + 50mm, a first group of electromagnets high gas boiler water level contacts the combined output high level alarm signal. 4. When the normal water level of the gas boiler -50mm, a second group of electromagnets in conjunction with the low water contact output low water level alarm signal.
