Commercial Gas Fired Steam Boiler Price
Depending on the operating characteristics of electric commercial fired steam boiler prices, mainly to properly regulate the drum and induced draft fan. The chamber negative pressure is guaranteed ± (5-10) premise mm water column (water column ≈9.8Pa 1mm) to minimize the amount of the wind, to extend the residence time of the flue gas temperature in the furnace, reduce exhaust gas temperature.
Water produced by the following factors: the temperature of the flue gas (91% in order to achieve thermal efficiency, the temperature of the flue gas needed to reach 170 ℃), where the total surface area of the heat chimney, chimney and chimney material. Maintenance of the burner. Electric commercial fired steam boiler price and burner maintenance, repair after steam supply. Because the products of combustion will corrode the boiler, clean up carbon deposits, therefore, not allow the products of combustion in the boiler memory stay too long. 3, clean electric boiler essential content.
Gas boiler installation and preparation requirements of (a) the preparatory work before the installation of a boiler installation must be installed by the unit has installed a license .. The installer must be familiar with "Boiler Safety Technology Supervision", and carefully read the installation instructions and other random technical documents. 2, a mounting position: 1) as close as possible to install a boiler steam, hot site, to facilitate shortening the hot water and steam pipes, reducing capital costs, reducing the pipeline heat loss. The installation site should be water supply, sewage convenience. Burning light diesel oil, heavy oil residue and the boiler must be closer to the oil reservoir; burning natural gas, town gas boiler must be easy to close the gas source. 2) boiler room layout should follow the "Boiler Safety Technology Supervision" relevant provisions "boiler room", to be well-lit, well-ventilated, no ground water, ease of operation and maintenance, boiler room must be equipped with at least two fire extinguishers 1211. 3) Check the boiler foundation, prepare the boiler in place. 3, equipment acceptance: acceptance by conduct an inventory purchase contract or supply list. 4, lifting large boiler: not less than 1.1 times the lifting equipment of large weight of the boiler, two lugs for the lifting jack top or at the bottom edge away slowly, not to any other parts of the lifting or addendum to avoid damage to the boiler. (Ii) installation requirements: 1, the main steam line installation requires the main steam lead pipe height is generally greater than 0.5 m, the bending radius should be greater than or equal to 5 times the diameter of the pipe, the pipe should be installed at the lowest trap, preventing water pipe, It should be a main steam pipe insulation. 2, a main return pipe installation requirements should the main return pipe elbow minimize installation, to facilitate the mounting operation of the valve, piping should be insulated. 3, the hydrostatic testing relief valve, the safety valve should be installed in the exhaust pipe, the exhaust pipe connected to the straight pipe outdoor safety. 4, should be connected to a sewage outfall tank or other security, the pipe should be secured to prevent shifting or counter scald accidents blowdown. 5, railings, stairs (with large oven) after the positioning by drawing the boiler installation. 6, water table must be installed to the lighting device, easy to install or inspection.
Recently, Luoyang City, Henan Province, pollution prevention campaign of the leading group issued a document required to carry out the transformation of low nitrogen gas boiler. Specific content: 10 before the end of the year, within the city steam 4 tons / hour and a gas boiler, and above all the installation of direct-fired burners low nitrogen, 3.5% oxygen in the transformation reference, more than 75% boiler load condition next, particulate matter, sulfur dioxide, nitrogen oxides emission concentration not higher than 5 mg / m, 10 mg / m, 50 mg / m. To complete the transformation of nitrogen oxide emissions monitoring, to wriggle out of the gas boiler outage low nitrogen transformation. After the new gas boiler should be installed low nitrogen burners.
