gas fuel fired steam boiler for food factories
How to solve the air pollution problem caused by food processing boiler operation for a long time, coal-fired boiler boiler industry occupies 90% of coverage, coal prices are not high for the economy is relatively backward areas, as well as coal-fired boilers do not ask, you can use low heat, high ash low grade coal. But with the massive emissions of coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boiler problems faced overhaul or banned. Food processing industry as the foundation of human existence and life, in the face of more stringent food processing caused by boiler exhaust pollution treatment, clean type of fuel gas-fired boiler choice of various food companies. Take the gas boiler, it is generally used natural gas as a fuel, natural gas use since it was developed, it is known to clean energy. The main component of natural gas is methane (CH4), carbon dioxide generated during combustion only (CO2) and water (H2O), only when the combustion temperature is higher than 1300 ℃ when nitrogen oxides (NOx) and other substances, but to bring the processing operation of the boiler the air pollution problem, prefer to use natural gas as a boiler fuel. Fast boiler since its inception, and be fully independent R & D of gas boiler, condensing technology, research and development and use of FGR and premix combustion flue gas recirculation technology, greatly reduce emissions of nitrogen oxides (NOx) and other substances, NOx emissions may be less than 20mg / Nm³, our first-tier cities to meet the most stringent air pollution emission standards, compared with conventional coal-fired boilers, gas boilers party soon launch more environmentally friendly, can deliver good quality for the food processing industry steam.
By burning and the like during combustion of the fuel to ensure complete combustion fuel fired steam boiler for food factoriess boiling water volume electrical means at night using low power boiler water boiled and stored in the insulating state. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Thus, a low-boiling nitrogen Burner electric device is an important fuel for industrial boilers and the gas boiler, which provides power to a small power people, and daytime combustion complete combustion of the fuel. Fengtai Electric boiling water into the boiler heat recovery boiler electric boiling water, boiling water boiler and continuous electrical breakdown electric boiling water boiler. 3. The principle of the burner is to shade a portion of the fuel burned too small, a small portion of the fuel burned too light, but the high air volume 360 remains constant. Since the two partial combustion deviated from a stoichiometric ratio, the NOx is low, also called the combustion or stoichiometric combustion variation. 4. The principle of segmented flame burner flame is divided into several identical small flame, because the small flame having a large heat dissipating area and a smaller flame temperature!
We learned from Anshan City Bureau of the ecological environment: to improve air quality living environment for urban residents, according to government requirements, Anshan external publicity of the built-up areas and industrial parks and a list of more than 10 tons of coal-fired boilers, municipal environmental protection department also welcome all citizens supervision, to provide the city's built-up areas and 10 tons and above boiler clues industrial park outside the list.
Battle to lay the blue sky, the city has in recent years embarked on a built-up area and the city's industrial park and 10 tons of coal-fired boilers out of work, the city built-up areas and industrial parks and 10 tons of coal-fired boilers demolition of all the reservation coal-fired boilers to achieve discharge standards. As requested, before the end of 2020 in the city of Anshan City will be built-up areas and industrial parks all phase-out over 10-20 tons coal-fired boilers, coal-fired boiler units involved should be prepared in advance.
To further enhance the quality of atmospheric environment, promote environmental management to raise the overall level, in accordance with the requirements of the provincial government, the city of the city within built-up areas and industrial parks and more than 10 tons of coal-fired boilers information for publicity. These publicity boiler will be included in the list of key sewage units, strict supervision, to ensure the discharge standards.
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.
