4 mw gas steam 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.

Our business-to-4 mw steam boiler produces steam attaches great importance to the quality of good or bad, it will indirectly determine the quality of our food is produced dates.

Vertical 4 mw steam boiler combustion characteristics combustion grate section with double action, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal. Gas steam boiler performance characteristics: 1, the furnace and comparing the old vertical boiler, heating area, rapid boost heating, less coal, high thermal efficiency, can save 25-30% of coal. 2, a furnace with multiple, user-friendly, the furnace can be used for the production of steam steaming canteens, disinfection tableware, bath heating, process steam, heating and the like locally heating the room. 3, the furnace with natural ventilation, induced draft fan and the blower does not need, no noise. 4, compact structure, installation, operation, easy maintenance, may be integrally handling, suitable flowability units. 5, heated with steam bath, food, heating, steaming, etc., pressure gauge scale strictly controlled within the design pressure, working pressure at any time shall not exceed the operating pressure. The scope of the steam boiler Application: can be used in textile, printing and dyeing, paper, food, rubber, plastics, chemicals, pharmaceuticals, iron and steel, metallurgy and other industrial products machining process required steam, and for enterprises, institutions, hotels, schools, restaurants, service industries such as heating, bath, air conditioning and hot water. Pledge: Since the equipment installation qualification pressure parts warranty 3 years, 12 months, auxiliary and lifetime maintenance, warranty period free of charge warranty for non-human failure (various defects caused by faulty equipment itself) of the Company, the replacement of damaged parts, the warranty period or man-made damage, is still responsible for maintenance and guidance equipment, for repair, replacement parts only fees. Quality assurance after the expiry responsible for maintenance of life.

Gas furnace gas and steam steam steam importance gas gas gas 4 mw steam boiler steam importance furnace gas and steam must sample tests, measuring visual quality of heat transfer fluids, flash point, viscosity, acid, water, and carbon residue, and certificate of quality manufacturing plant to provide heat transfer fluids are consistent, but also provide the basis for future changes in the operation of medium quality monitoring. Means passing the tests of the gas-steam heat transfer fluids using pumps to transfer fluids within the furnace and the injection of hot expander. When pumps heat transfer fluid to the injection system, should check again the furnace, heating equipment, piping system drain valve, drain valve is closed, in order to avoid loss of heat transfer fluids. While the exhaust pipe and the valve opening on the furnace one by one, to exclude air, until a closed gas steam flows. It stops when the oil level gauge appears on the expander injection heat transfer fluids, and then start the circulation pump, for circulating cold.
