gas diesel oil fired horizontal hot water boiler
Fuel gas-fired boiler fuel gas-fired boiler product presentation is different from coal-fired boilers, which requires the use of a burner fuel is injected into the boiler furnace using a combustion chamber without the use of fire grate facilities. Because not produce fuel ash after burning fuel gas-fired boiler, fuel gas-fired boiler so without slagging facilities. Oil injected into the furnace, if the gas and air mixture within a certain range, or turned off, it is easy to explode. Therefore, fuel gas-fired boiler combustion required to adopt automation and control systems. Fuel gas boiler compact, small boiler and ventilation, water supply, control and auxiliary equipment are arranged on a distribution box, it may also be assembled and medium-sized factory. Fuel gas-fired boiler safety valve installation points introduce fuel gas-fired boiler safety valve needs to be installed in the correct installation steps, in order to avoid mistakes, resulting in what needs to pay attention to danger, fuel gas-fired boiler safety valve installed it? Here, I introduce: 1 fuel gas boiler safety valve should prevent the lever means and movement of the self-weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly . 2. Rated to 0.5t h evaporation boiler fuel gas /, at least two safety valves installed; Rated evaporation 0.5t h or less fuel gas boiler /, mounted on at least a safety valve. The separable exit of the economizer, steam superheater outlet of the safety valve must be installed. 3. Fuel gas-fired boiler safety valve to the boiler tubes, cross-sectional area should not be less than the import safety valve cross-sectional area. If several valves installed together with a short tube directly connected to the drum, short tube passage area not less than 1.25 times the area of all the exhaust valve. 4. Fuel gas boiler safety valve should be installed vertically in the boiler drum, header high position. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm. 6. Fuel gas-fired boiler safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. Safety valve exhaust pipe at the bottom should be fitted to the safe location of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve.
Gas pressure diesel oil fired horizontal hot water boiler pressure introduction gas hot water boiler: gas pressure hot water boiler pressure vessel belongs, as always pressure hot water boiler is full of water, so no water level, but to be fitted with pressure gauges, safety valves and thermometers. Circulating pump pressure hot water boiler heating system is generally used in water pump, which is pumping systems engineering backwater sent to the boiler, it is necessary to overcome the resistance of the systemic circulation, but also to maintain a certain pressure boilers, hot water does not guarantee high temperature vaporization . Pressure hot water boiler can not only supply low-temperature water, but also to supply hot water Features: 1, boiler design, manufacturing, supervision and inspection are strictly according to "hot water boiler Safety Supervision" ensure long-term security and stability of the boilers. 2, the boiler body is a shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in combustion chamber a slight positive pressure, combustion heat load is low, less NOx emissions of harmful substances. Through advanced machine test bed to test several times to verify the boiler under various load operation can get good thermal performance, qualified flue gas emissions targets as well as a wide range of burner adapter. 3, before and after the boiler smoke box with a special heat insulation materials, high temperature, low thermal conductivity, good anti-radical quenching heat capacity, greatly extending the life of the smoke box. A lower smoke box is provided with a condensate drain, water condensed reduce corrosion of the pressure receiving member. 4, the boiler and each pot spout means disposed reasonable to optimize the pot water circulation, prevent scale generation, but also help to improve the water side heat transfer. Set hand hole, inspection hole in the poor circulation of weak links, to facilitate regular inspection and maintenance. 5, the temperature of the boiler smoke box structure compared to dry wet back boiler back, greatly reduced, the smoke box solves the frequent need to maintain the operation of the phenomenon; 6, a large volume of water boiler design, the load fluctuation of furnace not sensitive to large changes in the load range of users still apply. 7, industrial boilers professional artists and designers carefully designed appearance, novel and unique and yet with the surrounding environment coordination. Sino-Swiss boiler completely changed the image of heavy industrial boilers, industrial boilers is a new concept of low-carbon twenty-first century. Construction and installation points: 1 explosion-proof door is provided on the fuel, the rear of the gas-fired boiler or pipe smoke, explosion door location should be conducive to explosion venting. For gas explosion likely to endanger the safety of the operator occasions, should be installed on the guide tube pressure relief blast doors. 2. Installation of boiler and its auxiliary equipment, water treatment equipment should meet the technical requirements of the device manufacturer. Equipment foundation must be the arrival of equipment and after verification and design drawings before construction. 3. When mounting the device, the device should be avoided, to install the floor material are collected together. Column using a construction, the beam lifting device, must first verify that the carrying capacity of the beam, the column. 4. After the pressure test acceptance oil, gas, water, steam pipe installation, according to "Industrial metallic pipeline construction and acceptance" in GB50235-1997. The main construction practices and node configuration detail see National Building Standard Design Atlas. 02R110 "Gas (oil) boiler room engineering design and construction Atlas" 02R111 "small vertical, horizontal tank Atlas" 02R112 "Tank dome Atlas"
Matters needing attention in installation of Gas-fired BoilerGas-fired boiler also says that gas-fired heating boiler is a kind of boiler which uses gas combustion to heat water to satisfy people's heating. It belongs to the category of domestic boiler. By gas-fired heating boiler we usually refer to gas-fired atmospheric diesel oil fired horizontal hot water boiler, gas including natural gas, liquefied gas, city gas, coke oven gas, biogas and so on. There are explosion-proof doors on the rear of the fuel-fired boiler or on the smoke pipe, and the position of the explosion-proof doors should be conducive to the discharge of the explosion. In cases where explosive gas may endanger the safety of operators, a pressure relief guide tube shall be installed on the explosion-proof door. The installation of boilers, auxiliary machines and water treatment equipment shall be in accordance with the technical requirements of the equipment manufacturing plant. . The equipment foundation must wait until the equipment arrives and checks correctly with the design drawing before construction. 3. When installing the equipment, avoid the equipment, and the installation material should be stacked on the floor. When using building column, beam lifting equipment, the bearing capacity of beam and column must be verified in advance. 4. After installation of oil, gas, hot water and steam pipes, the pressure test acceptance shall be carried out according to the Code for Construction and acceptance of Industrial Metal Piping Engineering GB 50235 / 1997.
First Affiliated Hospital of Bengbu fully implement the national environmental protection policies, strict screening of clean boiler as the supply of medical supplies disinfection and ward heating equipment.
