Horizontal steam 2 1mw coal hot water greenhouse boiler with a boiler boiler you know take you through a horizontal steam boiler Generally speaking, we use boilers have very many models, according to their different fuels of different works, there are different, the boiler itself institutions, divided into many, the Take the steam boiler, there are still sub-ordinary boilers and steam boilers of it, for this horizontal steam boiler, his characteristics is not the same. Boiler fire resistant concrete arch from ramming. After the arch low and long, and therefore good combustion, flue wings and side wall refractory material sintered brick. Boiler front wall, back wall using a common bricks. Grate air distribution reasonable, the combustion chamber is large, strong coal applicability. Adapt to all types of bituminous coal or anthracite, mixed coal. Full combustion. Since the high temperature flue gas enters the first settling chamber, and then into the wings on both sides of the stack, before the smoke box, smoke and dust so good effect. Water circulation simple, reasonable structure and components under pressure, in the case to ensure water quality, completely safe operation. Combustion equipment for the quick grate, combustion apparatus installed in the manufacturing plant, transported to the site can be directly mounted on a foundation. With a reasonable structure, compact, low consumption of steel, the boiler performance, weight, frame size and capacity of the domestic product has obvious advantages compared. It is a horizontal type boiler quick fire tube boiler, refrigerant natural circulation. The boiler drum from the heat exchange system, the left and right header, composed of the water wall, the main furnace wall with a heating surface, convection tube inner drum portion and the drum.
Safety rules steam 2 1mw coal hot water greenhouse boiler steam boiler production, life indispensable important equipment. Boiler room is a vital part of my unit. Steam boiler having a high temperature, high pressure characteristics in use. Such as poor management, will be an accident, causing casualties, the production interruption caused serious losses to the school and state. So each time fireman and maintenance personnel to maintain a high degree of responsibility in their work to ensure the normal operation of the boiler, strictly adhered to. A strict compliance system fireman job, to play unity, mutual help support the spirit of love. Second, improve and maintain boiler equipment, keep boiler room tidy, attention and strive to save coal, water, electricity. Third, in the boiler operation to maintain a predetermined pressure, temperature, pressure must not exceed. Pay attention to discern false water level. Bearing in mind the piping, valves and the valve opening position of the distribution status of operation. Gradually closing the valve should be open or closed on the side of the handwheel. Always pay attention to the old boiler malfunction and run accident precursor, should understand the reasons for treatment and prevention of its occurrence. When the need for urgent and emergency shutdown. Keep in mind the role of the distribution board each button, leaving no more than a total pressure during shutdown and cut off the power supply. Fourth, coal hopper raised or lowered, the lower non-coal hopper to stand, the suction air blower, fan, Java machine, near the transmission gear portion, careful attention to production safety, to prevent accidents. Fireman must stick to work, and offenders a fine deal. V. PREPARATION carefully, to prevent explosive materials
Recently, Dongguan City, Guangdong Province, announced the embodiment of combustion facilities out of the transformation of coal-fired 2 1mw coal hot water greenhouse boilers. Continued efforts to implement air pollution control operations, blue sky to win the battle to raise the overall urban air quality, promote the construction of beautiful Dongguan.
Program execution object: the end of 2018 or for the gas central heating has been completed and all coal-fired boilers, furnaces, stove and other combustion facilities within the region.
Remediation program goal: to complete the gas before the end of 2018 has been for central heating or combustion facilities have been built out of regional coal-fired boilers and other renovation work. among them,
1, 2018 May 31, the gas supply has been built up, or central heating coal-fired boilers and other combustion facilities within the region, incorporating the first period regulation, must be completed before the phase-out renovation work in October 2018 31
2, June 2018 period from 1 July to 31 December 2018 for gas central heating area is built up or coal-fired boilers and other combustion facilities within the scope of the regulation into the second period, to be completed by 31 December 2018 out of the transformation.
Program remediation requirements:
1, the boiler must get out of the transformation of the city of Quality and Technical Supervision issued by the migration, retirement, cancellation of certificate or change a new boiler fuel use permit after; furnace, stove eliminated after the transformation of environmental protection must apply the change.
2, central heating is completed, it must use natural gas, liquefied petroleum gas, electricity and other clean energy combustion facilities outside the area out of coal-fired boilers, etc. after the transformation continued use.
3, central heating boilers planning area must use the central heating (gas) after the completion of the heating zone, will not have the heating conditions can use natural gas, liquefied petroleum gas, electricity and other clean energy as a transition.
4, into the "scattered pollution", high pollution and high emissions from industrial boilers and enterprise-wide to be eliminated.
5, for failure to complete boiler or eliminated within the rectification period, the Municipal Environmental Protection Bureau in accordance with the requirements of relevant laws and regulations and strict enforcement of its Municipal Quality Supervision Bureau will be canceled.
Steam 2 1mw coal hot water greenhouse 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.
