Natural Gas Hot Water Boiler


Natural Gas Hot Water Boiler

After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with the coal-fired boiler with the same parameters and capacity, the thermal strength of the furnace volume can be doubled to 1046.6 × 10 kilo coke / m / m ·h. However, in order to reduce the heat load in the combustor area so as to avoid the overtemperature of the water wall tube in this area, the furnace volume is only reduced by about 1 / 3. Because the ash content in fuel oil is very little, it can not form slag on convection heating surface, so the flue gas temperature of furnace outlet can be up to 1300 ℃, and the pitch between tubes of convection heating surface can be reduced to increase the flow rate of flue gas, so as to increase the flow rate of flue gas. Heat transfer coefficient of heating surface, saving heating area and steel.

"Professional life, work fine", which is the party adhere to the core values ​​of fast. Whether the overall boiler or details of the site, both parties soon to be subtle, not ignore every aspect. Single-minded attitude is a solid foundation for the development of innovation. Not forgetting beginning of the heart, was always square. Fang fast since its inception, adhere to the development road of clean fuel boiler, to respond positively to our policy, efforts to promote road boiler industry to environmental protection direction. Facing the future, parties will continue to fast innovation and creativity on the development of the first, and unswervingly take the road of clean and green, to provide users with a more secure and reliable boiler cleaning solutions.

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 hot water boiler 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.

Performance horizontal oil-fired boiler is now full of water and the handling of horizontal steam boiler steam boiler accident refers to a horizontal design, in accordance with the fuel divided into horizontal electric steam boilers, horizontal steam boiler fuel, gas steam boiler and lying horizontal coal-fired steam boilers. Horizontal steam boiler flue gas flow due to the long, slow smoke, high thermal efficiency, it is very energy efficient. Horizontal steam boiler filled with water treatment and now the performance of an accident, the phenomenon of (1) the water level is higher than the maximum permitted cable, or can not see the water level, water table within a glass tube (board) Color dark boiler full of water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
