energy saving industrial oil fired boiler
PRODUCT INTRODUCTION fuel gas-fired energy saving industrial fired boiler fuel gas-fired boilers and coal-fired steam boiler is not the same, gasoline and diesel and gas-fired burner must be poured into the fuel to the boiler furnace using a combustion chamber rather than grate facilities. Since the fuel gas-fired boiler is not easy to cause the fly ash lit, so no oil or gas boiler slag removal equipment. If mixed with air or exterminate within a certain range, it is introduced into the furnace petrochemical and gas easily the explosive. Thus, any gasoline and diesel and gas-fired boilers must be selected and automatic combustion control system. Compact boiler fuel gas, and the small boiler exhaust, drainage, control and auxiliary equipment installed at the distribution panel, and produce large and small boiler assembly. Fuel gas-fired boiler safety valve installation key point describes the installation of fuel gas-fired boiler safety valve sure to carry out in accordance with reasonable installation process, to prevent wrong and lead to risk. Fuel gas-fired boiler safety valve installation should pay attention to what matters? The following is a brief description: 1 oil-fired boiler safety valve having a lever bar to avoid self-weight and the mobile device guide body defining deviant lever, the spring valve lift handle and avoid the need for screw adjustment means random twist. 2. Rated evaporation than 0.5t / h gas boiler safety valve should be arranged at least 2, Rated evaporation gas boiler should be equal to or less than 0.5t / h, fitted with at least one safety valve. Separable economizer outlet and a steam superheater outlet valve should be installed. Sectional area of the connecting pipe between the boiler safety valve 3. Fuel gas boiler can not be lower than the imported cross-sectional area of the valve. If several valve mounted on each stub is directly coupled to the drum, the passage sectional area of the stub is less than 1.25 times not all of the area of the exhaust valve. 4. Oil and gas boiler safety valve should be mounted vertically in the height of the boiler drum and the header. Can not be mounted between the valve and the steam outlet conduit and the valve drum or header. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25 mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20 mm. 6. Fuel gas boiler safety valve should normally be established an exhaust pipe, the exhaust pipe should be directly connected security grounds, and there is sufficient cross sectional area to ensure the smooth flow of the exhaust gas. The bottom of the valve should be equipped with an exhaust pipe connected to the drain of a safe place. Valve must not be installed in the exhaust pipe or drain pipe.
The difference between the energy saving industrial fired boiler and the gas fired boiler oil boiler is one of the best among the devices communist essential, but is a new oil boiler heating equipment to heat conducting oil carrier, this actual boiler in use have a more favorable effect of heating and insulation effect, it is widely applied in more areas. In our gas and coal-fired boiler oil boiler has become one of the most widely recognized consumer products, and in the actual choice is due to the performance of the two products all have good performance, so you want to ensure the best selection of products must be to analyze the differences between the two products, the following small series give you an analysis of the most professional and coal-fired gas boiler oil boiler plant which respectively. 1. The combustion apparatus and media used for different well-known heating apparatus used in the gas boiler is a once-through special industrial furnace, the fuel used in such devices are some light oil, it is possible to ensure a more stable performance and fuel supply heating effect. When coal-fired heating oil boiler used is a thermally conductive grate, and this requires the use of coal in the boiler as a combustion medium, so the need to consume during actual use of more energy. 2. The effect of energy consumption and can be found among different consumers use energy much greater than the heat generated by the gas and more coal produced, under such different circumstances of heat, you want to make coal-fired thermal oil boiler to produce better effects associated with the required equipment dust blower machine, the higher the possibility of ongoing optimization of product upgrades energy consumption. And quality and reasonable use of gas-fired boilers continue to have the fuel tank and burner, and higher energy conversion rate of gas boilers, the use of oxygen by the boiler is also able to present a better heating effect. The above is the difference between gas and coal-fired boiler oil boiler, but can also be found in the use of these two products in the environmental performance have a big difference, because the gas after combustion will produce pollution gas, and coal-fired generating higher rate of dust and carbon dioxide, and therefore the use of gas-fired boiler has also become a trend collective heating in China.
Center back energy saving industrial fired boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas boiler SZS improve thermal efficiency because the oil, gas type SZS easy to burn the fuel gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature.
Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water energy saving industrial fired boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.
