boiler for plastic equipment production line
How do gas-fired steam boiler for plastic equipment production lines need to be maintained when they are not in use?
Nowadays, the use of gas-fired steam boiler has become more and more frequent, and the boilers all over the country have changed the use of gas-fired boiler with each passing day. Although the domestic professional gas-fired steam boiler is stable in operation and less energy-saving and consumption-reducing in sewage discharge, it is necessary to use proper maintenance in the case of long-term non-use in order to carry out normal use. Specific gas-fired steam boiler maintenance methods in the case of not in use and see below for detailed analysis of the following:
1: dry maintenance of gas-fired steam boilers should remove the boiler water after shutdown, and then thoroughly remove and rinse the dirt from the interior. And keep the oven dry so as not to be seduced. You can dry the chamber with a light fire, but not with a fire. Also be careful to close all hand-hole piping valves and place the quicklime tray in the drum. Check the boiler at least three months without using a gas-fired steam boiler for a long time. If the quicklime in the chamber is crushed into powder, the new lime needs to be replaced immediately to ensure that the drying protection in the furnace of the gas steam cooker is not corroded by moisture.
2: in addition to dry maintenance, wet maintenance of gas-fired steam boilers can also be done by means of wet maintenance, which is to remove internal dirt after discharging the water in the furnace, and to fill the chamber with treated water and then heat it to the required temperature. The gas in the water is then discharged out of the furnace and all valves are closed. In this way, the furnace is filled with water to complete maintenance. Of course, wet maintenance should not be used in cold weather to prevent water icing and damage to the tank. It can be seen that the gas-fired steam boiler in the case of not in use is mainly dry and wet method of maintenance, which kind of specific use Maintenance method according to different site and climate conditions to make flexible choice.
The party soon provide us with three hot water boiler for plastic equipment production line output foot, gas combustion, efficiency is very high, for us to save a lot of fuel costs. Moreover, these hot water boiler can be achieved by adjusting the full 24 hours a use hot water to meet the daily needs of old people. --customer feedback
Commercial Gas hot water boiler for plastic equipment production line how kind selection is more cost-effective? In the selection of boiler products, the price is we will first consider the question, then how about the selection of commercial gas hot water boiler is more cost-effective it? (1) the actual situation of the scene of the boiler, the boiler to determine a reasonable tonnage several. (2) Select the appropriate burner, and related auxiliary equipment configured according to boiler, in order to ensure the smooth and efficient running late and so on. Auxiliary avoid mismatch with the body, resulting in unnecessary loss of cost. (3) Further, the so-called cost, to take into account not only the actual parameter aspects of price, gas consumption, thermal power, thermal efficiency, emissions of nitrogen oxides reasonable quality, energy-saving operation late boiler cost will also be advantageous to be a reference standard selection of the boiler. Short for commercial gas hot water boiler is concerned, all parties should be strict requirements to ensure the rational and effective selection, run smoothly and efficiently, to ensure that we achieve a real sense of selection, acquisition and operation cost.
Pressure boiler for plastic equipment production line full of water phenomenon causes and treatment of pressure boiler full of water, when the boiler water level above the water table level security scale line, called boiler full of water full of water phenomenon is what causes it? How they deal with it? As follows: 1, when the boiler is full of water, in the water table often can not see the water level, but dark in the table, which is an important difference between full and water deficit. When filled with water, the high water level alarm alert operation; superheated steam temperature decreases; normal feedwater flow is not greater than the steam flow; severe, the water enters the boiler superheater and steam pipes, resulting in water hammer and superheater fouling. So the main hazard is full of water, reduce steam quality, damage that destroyed superheater. 2, filled with water common reasons: (1) operator negligence, strict monitoring of the water level or misuse: Run who leaves his post, abandoned the monitoring of water levels and other instruments; (2) failure caused by false water table level while not recognizing the operating personnel; (3) water level alarm and automatically adjust the water supply malfunction but not to detect the like. 3, found after pressure boiler filled with water: You should rinse water table, water table to check whether the fault, confirm filled with water, close the valve immediately to stop the Sheung Shui to the boiler. Enable economizer recirculation line, reduced combustion, open the drain valve and the superheater, the steam trap pipe until the water level returns to normal, close the drain valve and trap. Identify and eliminate the cause of the accident, adjust the water supply, to resume normal operation. If water hammer occurs when filled with water, the water level in the recovery, should also check the steam pipes, accessories, such as stents. These are the causes of atmospheric phenomena and boiler full of water treatment, boiler full of water or lack of water pressure in the boiler is running a common phenomenon, it requires fireman personnel taken to avoid such accidents.
