Steam boiler accident type and processing method, and use common sense safety boiler steam boiler accident type and processing method, overpressure accident 1 boiler, boiler overpressure phenomenon of (1) a sharp rise in steam pressure, exceeds the allowable working pressure gauge pointer over " red line "safety valve after the pressure is still elevated. (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, 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.

ZG manufactured chain grate hot sale coal burning hot water boiler for food factory has joined Global Environment Facility (GEF) project. To meet environment standard, experts in ZG Boiler keep innovations and technology developments and successfully launched 1 to 120MW hot water boiler. Our hot water boiler also has widely fuel availability such as coal, biomass, wood, gas, oil, etc. The boiler is supported by the angle tube with high assembly level, but without the steel frame, and it reduces the installation workload at site. The reasonable grate structure and the good air flow adjustment capability ensure the complete combustion and reduce the mechanical incomplete combustion.

Why regular cleaning hot sale coal burning hot water boiler for food factory: hot water boiler can be divided into many different depending on the application, tea and hot water boilers, hot water boilers, and so on. But each boiler after a period of time necessary to carry out regular clean-up, so as not to affect the normal use of the service life of the scale and the usual hot water boiler. Boiler water contains small amounts of salts, suspended solids and gas, the presence of these substances can cause such accumulation, corrosion performance, some time after the operation of the boiler water side will bear a small amount of calcium magnesium carbonate scale and corrosion and other products, these rugged dirt attached to the exterior of the boiler, resulting in improved heat transfer, increased coal, affect the operation of boiler efficiency, leading to higher economic losses to the safe operation of the boiler caused serious harm. Pickling descaling boilers necessary to stop the current, and finally to the inner wall of the boiler water clean side clean coal utilization rate of progress, while saving a small amount of coal, increased environmental pollution, extend the service life of the boiler. That the above things, you should understand the need for regular cleaning of the hot water boiler okay. Optimistic about the boiler safety valve, to ensure safety.

Special equipment to do the field work safety supervision, to further improve the boiler enterprise security management, implementation of corporate safety responsibility; March 13, Gaomi City, Shandong Province Security Committee held a boiler corporate safety training sessions. The meeting was attended Market Authority official in charge of the business section chief; towns full-time deputy director of the Office of District Administration of Work Safety; 402 boiler business person in charge, the Boilermakers; 157 appliances can replace the user responsible for the project.

The meeting of business leaders and boiler related use Boilermakers were safe to use boilers special training. At the meeting, Municipal Emergency Bureau is mainly responsible for a speech, requires the use of boilers enterprises to strengthen security awareness of employees, improve the professional level of employees, establish and improve mechanisms to ensure the safe operation of the boiler.
