PRODUCT INTRODUCTION fuel gas-fired boiler fuel gas-fired boilers and coal-fired higher steam quality 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.

Risk factors for gas higher steam quality steam boiler steam boiler gas boiler risk factors get in the industrial field has been widely used. However, the safety of heat transfer oil boiler has been neglected. Safety heat oil boiler is not only related to the normal operation of the plant, also related to the safety and efficiency of the staff of the enterprise. security issues heat transfer oil boiler should be aroused widespread concern in the community, its vital security issues. pot body portion and a body portion of the furnace for gas-fired boiler, the occurrence of physical experience pot explosion. for liquid boiler, the boiler combustion flame in the furnace section, if the boiler burning coal, there will be a burning fire, gas and fuel boiler chemical explosion. gas boiler is a highly dangerous material having high temperature, high pressure, flammable, explosive and other characteristics. in practice, these reasons, we could cause some problems negligence or illegal operation, so inevitably lay hidden dangers. first, you must ensure that safety heat transfer oil boiler. in use of the device, the device needs to be checked regularly to ensure that the heat transfer oil boiler heating system in good shape , The strength of the wall of the pressure equipment and devices to check that there is no problem; Second, employees must strictly follow the instructions Due to the special nature of the gas steam boiler, inflammable and explosive materials pose a security risk, the operator must be trained. familiar with the device structure, operating strictly in accordance with the articles of association; third, to ensure that the gas does not mix with water vapor gas steam can not be mixed with low-boiling substances and explosive substances, otherwise the consequences could be disastrous.

How to improve the thermal efficiency of gas higher steam quality steam boiler steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
