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.
Hot water boiler fuel oil hot water boilers brief automatic control system has a high-tech, with a number of security devices, water protection, overpressure protection, flame protection, abnormal pressure protection, over-temperature flue protection; structure using tech, having a body holding a small, compact and easy to install, easy to operate, automatically adjust the pressure of the fuel to the atomizing, a slight positive pressure of the combustion so that fuel combustion and then more fully, and to reduce the loss of the fuel gas discharge, modern industrial steam is the most convenient and most energy-efficient, environmentally friendly standard products. The need for comprehensive maintenance of the gas hot water boiler gas hot water boiler for normal use, to do regular inspection and maintenance, however, has been used for a three-year-old boiler, we must conduct a more comprehensive repair work. 1, carrying out comprehensive maintenance check, the first thing to be clear inside the boiler ditch and sludge, after using water to rinse these ditches and sludge. 2, the boiler for burning site, there will be a large amount of soot and fouling, but also in such substances when overhaul, the cleanup process. 3, because the gas hot water boiler is used in metal processing and production, but also a lot of contact with water or steam, it is inevitable there will be erosion situation, when the boiler overhaul, to the corrosion phenomena boiler maintenance treatment Finally, we need to do to level the boiler fire boiler use paint protection to prevent future corrosion conditions.
Temperature protection device during the fuel china wns horizontal internal-combustion-fired steam boiler over temperature to regulate protective effect of temperature protection is an important procedure fuel steam boiler safe operation is particularly important for the regulation and protection of the boiler temperature of the fuel vapor; at the same time to regulate in the fuel steam boiler overtemperature Protective effects. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: prevent explosion of the furnace, steam boiler fuel flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds reignition monitoring the furnace, a second the run off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off and various auxiliary blowers supply the boiler operation stops. role is to monitor the flame signal the presence of a flame or an interrupt control apparatus mainly using a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type a photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation strength of current and the linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.
