Gas Fired Boiler Of 15 Tph Steam

What is the main danger steam fired boiler of 15 tph steam? The main danger emergency steam boiler 1, surveillance, hazard control boiler steam boiler regular inspection tours, and monitor pressure, water level, temperature and combustion conditions to control the boiler operating conditions. And to take timely measures to ensure safety. 2, the processing operation of the steam boiler in special circumstances: (1) water shortage phenomenon: When the boiler water, the water level below the water table level limits not visible, low water level alarm emits an alarm, bell lights, low interlocking means so that the water level blower, fan, etc. closure operation; boiler exhaust gas temperature rise, a serious lack of water, lake taste top coke production, the door can be seen from the red-hot waterwall tubes, tube deformation or even explosion pipe, can be heard blasting sound, smoke and steam discharged from the door to see the fire door. Treatment: When judged as a serious water shortage, should an emergency shutdown, non-serious water shortage boiler water to the boiler. Immediately stopping the supply of fuel, the wind stops blowing weakened, the front portion of the coal grate furnace Pa, the maximum switch the grate, combustion slag hopper falls quickly, with irrigated off, after extinguishing the fire, stop the wind, open ash door, the door to promote accelerated cooling. Note: Do not feed water to the boiler, shall take measures to prompt blood pressure, prevent the accident, to refrain from watering methods to the furnace fire put out the fire. (2) boiler overpressure phenomenon: a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line", the safety valve, the pressure is still elevated, issued overpressure alarm, steam temperature and steam flow rises cut back. Processing: weakened rapidly burning, manually open the vent valve or safety valve, to increase the water supply, sewage increase (normal water level at this time to keep the boiler), thus reducing the temperature of the boiler water a boiler drum pressure decrease. (3) boiler tube phenomenon: the waterwall tubes blasting significant audible pops or jet sound, until the furnace by the combustion pressure becomes the negative pressure combustion, flue gas and steam and has viewed from the fire door, the door does not close, etc. discharge, although the water supply amount is increased, but difficult to maintain the normal water level and the pressure reduced, the amount of water to abnormally greater than the amount of steam, the exhaust gas temperature decreases, the chimney white smoke, the furnace temperature is reduced, or even extinguished, water flow out of the bottom of the boiler. Treatment: furnace tube rupture is not serious and can maintain the water level when the accident not to expand, may reduce short-term load operation, serious burst pipe and the water level can not be maintained, must be an emergency shutdown. But the wind should not stop, should continue to Sheung Shui, lower wall temperature. Such as: lack of water wall overheating, while burst pipes, emergency shutdown should be prohibited to the boiler feed water, the withdrawal of the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of superheating boiler. (4) steam boilers will produce full of water, such as priming scene of the accident, should take timely and effective measures to eliminate given. (5) boiler operation, in the event when one of the following circumstances, should immediately shutdown :( a) boiler water level below the lowest water level gauge visible edge; (b) increasing water supply and other measures, but the water level continued to decline; (iii ) boiler water level exceeds the highest visible level, the drainage can not see the water level; (iv) to pump all the water system failure or malfunction, not bottled water to the boiler; (e) all of the water table or valve failure; (vi) is set in a stripping all space gauge failure; (vii) damage the boiler element and endanger the safety of operating personnel.

Boiler is how the classification? Press export steam parameters of how to classify? Classification of the fired boiler of 15 tph steam is very extensive concept from different angles have different classification, can be classified by application area, according to the export media classification, but also by the pressure of the boiler classification. If the classification parameters according to the steam outlet, then find out which parameters steam boiler, wherein the boiler comprises evaporation, steam pressure, steam temperature etc., and is classified according to the main points of the outlet steam pressure: low pressure boiler (P <2.5MPa ), pressure in the boiler (22.5

Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type fired boiler of 15 tph steam paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.

10 t 10 t introduce gas fired boiler of 15 tph steam gas boiler steam boiler dedicated configuration computer controller, all Chinese, a large screen, backlit LCD display strong, rich display, operating status of the controller and the collected pressure, water and other states may be accurately visually displayed. Complete control functions, with intelligent boiler water level control, steam pressure control, low-limit water level alarm and interlock protection, high water level alarm, ultra-high pressure steam alarm and interlock protection, automatic control functions. Very convenient to use, may be provided continuously, the timing of the two states, the timing can be divided into four time periods, the boiler regular boot, time off, without full fireman, usually only have to press the start key turned on, press the stop button to stop very easy. Features: imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, low NOX, energy saving . Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. Advantages 1,10 tons of gas steam boiler furnace design and manufacture Three-pass boiler, wet back, eccentric furnace, asymmetric structures, waveform furnace, so that the flame produced a strong disturbance, and increased radiation heating surface, increased strength heat transfer coefficient, and can effectively prevent metal thermal expansion and contraction resulting in reduced life of the device. 2, the whole high degree of automation, security improved. Run fully automated process, with automatic replenishment, water shortage, overpressure, automatic power off and alarm, leakage protection and other security systems. 3, the whole body as glass wool type insulation, light weight, good thermal insulation effect, less heat loss; protection system: (1) protect the boiler water level indicator and integrated design of the boiler, the appearance of a more compact appearance, function accurately display the boiler The actual body of water. Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
