Horizontal hot water boiler with and oil fuel a few precautions, overpressure accident 1 boiler, steam boiler overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with 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, steam 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.
How to prevent gas hot water boiler with and oil fuel explosion gas hot water boiler belongs to the category of special equipment, thermal equipment and is a frequently in high pressure high temperature state, it is inevitable some small problems that may occur during operation, this is normal; but if not in place or because of negligence, they are likely to make the boiler exploded. So, for safety equipment and personal safety, we have to understand some common sense prevention hot water boiler explosion. 1, hot water boiler furnace explosion prevention occurs first on the boiler design, should be strictly thermodynamic calculation and strength calculation in accordance with the requirements of GB50041-1992 "boiler room design specifications", the structural arrangement should be reasonable, material quality should meet the requirements. Boiler manufacturing, construction plans should ensure compliance with national quality boiler scale delineation. Boiler safety accessories should be complete, agile and reliable, and maintenance schedule, often check on the failure of the attachment timely replacement. Schedule for maintenance of the boiler, the outer part of the boiler maintenance, subject to the existence of timely repairs and reconstruction to ensure test quality standards. 2, prevention of fuel, gas hot water boiler furnace explosion at the point of blast furnace to double-check each gas line, oil line is tight (leak), pressure is normal, Installation and reconstruction of new oil and gas pipelines necessary to purge and clean. Check the ignition lead before the drum whether the fan has to take the air 5 ~ 10min, after ignition failure to analyze the reasons, and then restart the ignition process to take the air ignition. Boiler use permit and inspection certificate did not apply for the boiler, furnace stokers right to refuse point. Enterprises should choose a fireman permit manipulation of experienced fireman point-furnace work, fireman staff should strengthen the inspection tour, identify problems in time to prevent the flame; flame once found, should immediately cut off fuel. Boiler installation should be controlled protection device, comprising an automatic ignition, flame protection, automatic adjustment of combustion and the necessary alarm chain protection.
So how versatile industrial boilers for energy saving? First, the fuel added through the fuel economizer process various compounds economizer its internal molecular structure will produce changes in the viscosity of the fuel increases the distance between the molecules and the molecules decreases, complete combustion can be performed prior to refining to maximize atomization and so that combustion within the environment can be the most complete combustion, can reduce the heat from the flue more so that the temperature of the flue decreased. Added industrial boiler economizer and may eliminate the tar oil and the combustion secondary coking can be prevented, to prevent incomplete combustion of combustion leaving the furnace wall phenomenon, can achieve high energy saving effect. Second, add condensed industrial boiler economizer section at the time of exhaust of water vapor occurs, they can be utilized with great resistance, they can be fully utilized by the installation of the condensing economizer. Industrial boilers condensing economizer may be mounted through the flue of the boiler, it can effectively recover the energy available in the flue gas, the fuel is reduced defeating by condensation of water vapor in the flue gas absorption compound absorption, reduce pollution emissions have higher environmental awareness. Third, the exhaust heat recovery in high temperature industrial boilers, flue gas containing water vapor has been heat will be in state, not condense into a liquid flows out, part of the flue heat may be collected charged by the waste heat recovery apparatus again use, to maximize the energy use.
Condensing a portion of the air preheater and use of double combination economizer design. Internal economizer heat exchanger elements using the new technology - the wings of the tube instead of finned tubes, a five-fold increase in heat transfer area at the same volume, latent heat of vaporization of the portion of the flue gas is sufficiently absorbed, effective utilization of the fuel energy, energy saving at the same time enhance the efficiency of the use of the boiler. Air preheater is further absorbed by the air and the flue gas convection heat latent heat of flue gas, and the air heated by the air preheater is connected directly into the burner tube, providing warm air for the fuel, thus improving combustion efficiency. This exhibition brings Chinese fast "Euromonitor" series boilers attracted a large number of customers, to give customers unlimited. Here, fast Boiler staff wish the exhibition every success.
