4 ton steam boiler Manufacturers Commercial Singapore

Six days this month, Changsha, Hunan Furong District Arts Road street to carry out special safety inspection of boilers.

Inspectors focus on examination of the health and safety management of boiler equipment, whether or not the gas boiler passed the test, whether to establish safety management systems and procedures, whether set the security authorities, whether with full-time security officer, determines whether the operator a valid work permit for employment, boiler operating records, inspection records and shift records are complete and so a detailed investigation, while eliminating the risk management and operational aspects of the boiler in existence.

In this inspection, the implementation of the following three major check the contents.

First, we must implement the main responsibility for security, strictly abide by relevant laws and regulations and safety specifications, and resolutely put an end to illegal operation, strengthen the management and monitoring of equipment, hazard, earnestly implement the responsibility to the people, and ensure safe and reliable operation of special equipment.

The second is to strengthen the advocacy training for boiler operators to improve their ability to deal with emergency breakdown or accidents, improve safety awareness boiler operator, firmly establish the concept of safety first, to ensure the safe operation of the boiler.

Third, low nitrogen and urge reconstruction work carried out boilers to reduce nitrogen oxide emissions, reduce concentration of nitrogen oxides, air pollution prevention.

Henan gas boiler to start the process of how to control the drum water level during startup Henan gas boiler drum water level should be adjusted according to changes in the status of kotelshchik control. (1) the initial ignition, Henan gas boiler pot of water gradually heated, vaporized, expanded, the water level rises, this time not by accident turn on the water to reduce the water level door, and the door should be regularly sewage discharge, can increase the pot of water quality, and promote water cycle. (2) With the increase of steam pressure, steam temperature, the amount of exhaust is increased according to the trend should drum level, replenish the water supply. (3) performing Henan gas boiler when the red tube or security check gate, often due to a sudden increase in steam flow, steam pressure and cause serious downhill "false water level" and, therefore, should be preceded by performing the above operations remain low water level, and then increase the water supply according to changes in the flow of steam, causing the water level is too low to prevent the safety valve seat and other reasons. (4) The load condition Henan gas boiler, the feed line switching operation in a timely manner, and in accordance with a predetermined condition, into the automatic water supply device is operated.

How to distinguish between pressure hot water boiler heating system and hot water boiler pressure hot water boiler should consider the establishment of good early pressure system or pressurized system, then these two hot water boiler heating systems What is the difference it? pressure equipment as boiler heating system in (1) pressure hot water boiler, there will be an explosion hazard situations. Boiler pressure hot water boiler heating system is not under pressure, China Unicom and the atmosphere is always, therefore boiler explosion will not appear in any case, the safety performance is good. (2) If the pressure hot water boiler is filled with water, the water level control is not control the phenomenon. Pressure hot water boiler water level control will exist related issues. The boiler is filled with water, still connected to an open top of the box, there is still water level control problems. (3) pressure gauge, a thermometer and safety valve must be installed on the pressure hot water boilers, such boilers and boiler because always is full of water and the water table is not set, and the atmosphere is only hot water boiler water meter and thermometer, because the boiler connected to the atmosphere, the pressure pot is always atmospheric pressure, no risk of explosion, there is no need to install a safety valve, pressure gauge does not require installation. (4) pressure hot water boiler heating system for the circulating pump to the boiler return pumping systems engineering, water pump is generally used. Necessary to overcome the resistance to circulation system, but also to maintain the boiler pressure, the boiler to ensure that the water does not evaporate at high temperatures.

Hot water boiler soda treatment guidelines have soda water boiler surface is more annoying things to look at how to deal with today. First, the boiler evaporation surface (surface) rises soda together, shake up and down the occurrence of a lot of foam and roll scene, called priming. When priming occurs, the water table is also frothed, sharp shaken water, soft drinks is difficult to distinguish the boundaries; sharp decline in temperature superheated steam; when severe, water hammer occurs in the steam pipe. Priming of the full consequences of the same water, with water vapor will decrease the quality of steam, superheater fouling and formation of water hammer oscillation, damage or affect the safe operation of the superheater steam equipment. Second, the soft drinks were vacated, have composed the following two factors: 1) poor quality water pot. Due to poor quality of feed water, sewage and other factors wrong, formed pan suspended in water or salt content is too high, the base is too high. Due to the higher-containing soft drinks near the parting, boiler water concentration of the surface layer, a large pot of water viscosity, bubbles rise to the resistance increases. When the load is added, increased vaporization, many adherend bubble barrier layer in the vicinity of the water surface too late pot leave out a lot of foam constituting the water surface of the pot roll up and down. 2) adding a load and rapid pressure drop. When the water level is too high, excessive load is added, the pressure drops too fast, the evaporation surface will increase, the water formed and shaken with water vapor. 3) Adoption of the approach found Priming: at the moment of combustion should be weakened, drop load, small off main steam valve; hydrophobic reinforcing superheater and steam pipes; fully open the drain valve after another, and turn on the water drain valve open as expected, Sheung together, to improve the water quality of the pot until the water quality improvement, water level clearly can gradually recover normal operation. Third, to prevent the priming approaches: 1) strengthening the management of water quality, strict control of boiler water salinity and grease, suspended solids; 2) according to boiler water analysis, successive emission control; 3) open to the main steam supply should be slow steam valve; 4) and the boiler steam pressure should be lower than the base pipe pressure 0.05Mh; 5) put into operation before the new boiler must cook oven. There is the above method of treating the surface of hot water in the soda boiler.
