Henan burner safety control requirements two gas central heating boiler intermediary 1, the boiler burner gas Henan Henan power protection gas boiler burner sudden power failure during operation, must be immediately cut off the supply of natural gas to protect the security device. Gas control solenoid valve must be normally closed, power down, automatically cut off the gas supply. Solenoid valve closing response time ≤5s. 2, Henan measures gas boiler gas burner preventing leakage of gas leakage accidents include two aspects, it refers to a gas leakage into the environment, for the finger furnace gas leakage through the line by the solenoid valve spool end. Environmental leaks can cause poisoning, work-site explosion, must attach great importance. First make sure tubing sealed, regular pipeline leak detection, pipeline leak to be ruled out if the can continue to use; secondly, to avoid the concentration of gas poisoning and explosion, requiring the work site is well ventilated: Configure permanent vents and forced ventilation means; Further, requires work site prohibit fireworks, explosion-proof electrical parts. Furnace furnace leak could cause an explosion. There are three ways to solve the leakage problem furnace: First, strengthen hair and the amount of pre-blowing time, or blowing furnace gas dilution; Second gas line using two series arrangement of a solenoid valve, to improve system security; Third line using leak detection means for detecting the gas line before ignition, gas leakage if a certain amount of work and lock the burner. Gas leak prevention measures is a peripheral control, are generally not included burner body control.
Our emphasis on increasing green, local governments also central heating boiler intermediary operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
How do gas-fired steam central heating boiler intermediarys 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.
