2 sets gas fired hot water boiler project in tunisia

Combustion gas treatment and a malfunction due to gas boiler burner ignition misfire bar: 1, the ignition bar gap interposed carbon residue with oil. 2, ignition rods fragmentation. moist. Leakage. 3, the distance between the ignition does not stick, too long or short. 4, ignition rods Insulation damage, short to ground. 5, ignition cable and transformer failure: cable, connector damage caused by a short circuit during ignition; transformer break or other fault occurs. Gas Burner fails, the action bar ignition misfire following five: Clear, renewal, adjust the distance, change and switching transformer. Second, the gas boiler the ignition spark rod misfiring but the reasons: 1, the disk space ventilation carbon cyclone is blocked, poor ventilation. 2, dirty oil nozzle clogging or wear. 3, the throttle angle is set too small. 4, the firing bar from the leading edge from the oil nozzle tip inappropriate (too protruding or retracted) 5, the first solenoid valve is an oil debris blocking gun (gun small kerosene). 6, oily or too viscous to flow easily clogged or the oil filtration system the valve is not opened, so that insufficient suction pump, oil pressure. 7, the filter pump itself blocked. 8, the oil more water (boiling abnormal noise within the heater). Gas boiler ignition spark rod action but misfiring are: clear; the first washing, such as not renewed; turndown test; adjusting the distance (in 3 ~ 4mm as well); Remove cleaning (cleaning the parts diesel) ; check the pipeline and oil filters, insulation equipment; peripheral screw pump removed, carefully remove the cover inside out net oil, diesel oil immersion; renewal of the test oil. Third, when the gas boiler and turn the fire a small fire normal, off, or flashing the causes of instability: 1, air volume damper setting fire too. 2, oil fires micro switch valve (damper outermost that group) inappropriate setting (set throttle air flow rate is greater than the fire). 3, oleaginous easy to spray viscosity is too high (heavy). 4, and the nozzle plate spacing cyclone inappropriate. 5, fire nozzle worn or dirty. 6, the preliminary fuel tank temperature is too high, so that the steam not smooth oil pump oil feed. 7, gas 2 sets fired hot water boiler project in tunisia fuel oil water. When a small fire gas boiler normal and turn the fire extinguished or flashing instability action: Test gradually reduced; heating temperature; adjusting the distance (between 0 ~ 10mm); clean or replace; i.e., set to about 50 deg.] C may be; or drain oil change. Fourth, the noise increases gas boiler burner reasons: 1, cut-off valve is closed or the passage into the fuel shortage, an oil filter blockage. 2, the oil inlet temperature is low, the oil viscosity is too high or the temperature is too high the pump inlet. 3, oil pump failure. 4, fan motor bearing damage. 5, dirty fan impeller. Burner gas treatment increased noise: ① the check valve in the oil line is open, if the oil filter is working properly, the filter cleaning pump itself. ② heating oil or reduce the oil temperature. ③ Replace the oil pump. ④ replace motor or bearings. ⑤ cleaning fan wheel.

Temperature protection device during the fuel steam boiler overtemperature protection to regulate temperature protection is an important part of safe operation of steam boiler fuel, especially fuel steam boiler temperature regulation and protection. Electric heating boiler and the boiler is mainly composed of electric control box and control system. Its characteristics are environmentally friendly, clean, no pollution, no noise, automatic, with limited energy and reduce prices significantly, as a new boiler electric heating boiler equipment increasingly being recognized. Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. Meanwhile, when the superheated steam boiler fuel, can play a role in the regulation and protection. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: To prevent the furnace blast, the fuel steam boiler must be equipped with flame protection device, and its function is combustion within the monitor cavity (including ignition misfire on or off in the middle of the combustion, is generally re-ignition within 5 seconds, within 1 sec. running off the oil (gas) solenoid valve, and opens the concurrent silent alarm signal, when the blower continues to operate, remove residual combustible gases in the furnace, after 20 or 30 seconds purge, and various auxiliary blowers automatically cut off power boiler stop running. flame monitor function signals displaying a flame presence or interrupt from the control device. its main use is a photomultiplier tube, photoresistors and photocells, they have an ultraviolet or infrared type photoelectric conversion element, its operating the principle of light radiation intensity is converted to the corresponding high current and low current and the output is a linear state, the induced current is sometimes weak, and thus affect the controller amplification.

Select the fuel gas-fired boiler when what issues should pay attention to it? With the National Energy Bureau of Statistics figures out show that China's coal reserves are decreasing year by year, has been unable to meet our daily consumption, then the traditional coal-fired boilers will be gradually out of the market, a new type of fuel gas-fired boiler will become the new main force, then we choose the fuel gas-fired boiler when what issues should pay attention to it? Xiao Bian gave you about the advantages of the river south fast fuel gas-fired boiler is reflected in What: Henan party soon, Ltd. manufactures compact gas-fired boiler fuel, boiler and ventilation, water supply, control and auxiliary equipment are provided on a chassis as possible for customers to free up more space. The advantage of this is that while the boiler is compact but its capacity is not small, hot water and heating range is not reduced because of the small volume. Main pressure connection element Henan local fast fuel gas boiler are as follows: 1, the main fire tube boiler pressure parts: the center back to the combustion chamber, boiler shell, a tube sheet, furnace, pipe tobacco, smoke box; 2 main pressure element water tube boilers: drum (drum), the waterwall tubes, boiler bank, serpentine tube header; 3, the main pressure connection element fuel gas boiler: the main welding, also part expansion may be.
