The main difference between the fuel gas boiler thermal control of the basic requirements of fuel gas boiler room in claim 1. The thermal control of the basic fuel gas boiler fuel gas boiler main features of the gas boiler grate firing combustion system is different in that, mainly in the nature of the fuel and combustion different. Fuel gas boiler combustion system has the following two characteristics: 1) If not properly controlled combustion process, the furnace can form a large number of combustible gas mixture, when mixed gas deflagration, the furnace may cause an explosion, causing heavy casualties and property losses. 2 combustion) of fuel gas boiler combustion space, the combustion speed, load responsive. 2. controlled boiler fuel gas and fuel gas requirements of the boiler combustion system adapted to, the following basic requirements for the fuel gas boiler automatic control system: (1) reliable system configured to prevent fuel gas boiler explosion, the design of the fuel gas boiler when automatic control system must be designed to give priority to the reliability of a system, the detection system may employ protective control system provided separately, if necessary. In the selection of microcomputer control system, it is necessary to adopt a dual configuration instructions manual and the necessary back-up of important parameters such as measures to improve the reliability of the control and protection systems. (2) starting the program control strict fuel gas boiler shutdown should process control, rigorous testing of the fuel during the start-stop system, air supply system and a flame monitoring system, since a failure to avoid the shutdown process. (3) timely protection should be reported depending on the circumstances, the choice of the following associated with the combustion system alarm and interlock protection projects: 1) drum level limit alarm and interlock protection. 2) Overpressure drum (temperature of hot water for boiler overtemperature) alarm and interlock protection. 3) flameout interlock protection. 4) Low oil pressure interlock protection (oil-fired boiler). 5) high oil temperature interlock protection (oil-fired boiler). 6) low oil temperature interlock protection (oil-fired boiler). 7) Low gas pressure interlock protection (gas boiler) 8) Interlock high gas pressure (gas boiler). 9) wind down interlock protection. 10) Burner flange interlock limit switch. 11) combustible gas leak alarm. 12) earthquake interlock protection. (4) a fast system response when running the fuel gas boiler abnormal combustion flame is off, the automatic control system required to be quickly cut off the fuel supply, to prevent the fuel into the furnace, thus requiring automatic control system fast enough response speed. (5) When the load adjustment linkage fuel gas boiler load changes, fuel regulator response speed faster than the response speed of the air supply system. When the load suddenly increases, the rate of increase of fuel greater than the corresponding rate of increase in the amount of air, resulting in incomplete combustion, soot is produced; when the load is reduced suddenly, fuel reduced speed, resulting in high oxygen smoke. For small boiler-off control of combustion increase or decrease should match the amount of increase or decrease in the wind, or it may cause flameout. Thus in the design of automatic control system, should be considered synchronized adjustment of combustion air. (6) field instrumentation for explosion-proof gas boiler automation systems, field instrumentation should be used in explosion-proof instrument.

Thirteen Five release plan indicates that China's move towards green development pace firmer, Beijing SASAC Building Materials Service Center from its start, the use of green boiler heating for low nitrogen as the primary task before the onset of winter. SAC Building Materials authorities after preliminary investigation and after the screening, the other fast boiler R & D experience in the field of boiler cleaning two decades expressed appreciation can, in August 2017 signed a five Thalia T6 series one boiler and two vacuum with fast Boiler condensing gas boiler products contract.

How to reduce the scale of known gas steam boiler steam boiler heating surface of the machine is the primary supply of high quality steam. Past, steam appeared to mankind brought great changes. The emergence of the steam era of human civilization introduced the modern era. Now there steam boiler once again that human potential is unlimited, it appears there are a lot of people to help. Steam boilers plays an important effect on people's day in. It's like bathing, eating, and other industries. It is said that the local demand for steam boiler steam demand. Steam boiler steam supply is the primary tool. Industrial production in the steam boiler to supply steam for the people, with the production of human power supply, making it easier to produce in the production. In the days of steam boiler supplying steam can help people make food, why we can take a bath with a steam boiler in the cold winter. These are to help supply the steam boiler. Steam boiler steam can easily supply better for us to make our life easier and more convenient. About steam boiler, we should be careful when they use their maintenance work, so that it can help us longer. Steam boiler in direct contact with the heat exchanger, the high heat recovery, contaminants in the flue gas are also removed, but acidic water quality, which is not convenient for the commercial fired horizontal hot water boiler seller. The so-called direct heat exchangers is that we often call for means for recovering heat from the flue gas condensation. Now, more and more people choose to use the steam boiler, the share of the market share continues to add. Flue gas discharged from the steam boiler containing a lot of water vapor, is condensed through the release of a lot of the latent heat of vaporization, which is more than a coal-fired boiler. a lot of. This boiler better selection of direct heat exchanger. Industrial production is the primary driving force of the world expanded, is very important for the expansion of the world. Therefore, we need to use steam boiler supplying steam better for us, because of our human expansion needs of these sophisticated machines help. No machine age is primitive society. When humans learn to use tools, it marked the beginning of civilization has already begun. Steam boiler is a tool we humans can do to help expand. No matter how preparedness, gas steam boiler, after working long hours, more or less will have some scale. Gas steam boiler is in operation, the furnace will be a series of chemical and physical reactions, the application process, will form a strong and fine scale on the heating surface, which would lead to a direct heat exchange efficiency of the boiler decreases; and by the effects of corrosion under the scale, will lead to reduced water wall furnace heat absorption gas steam boiler, then dropped thermal efficiency, waste of capital investment. The necessity of finishing scale there is little that is durable stable job and let the boiler down. As long as the thermal conductivity of the scale of one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, in order to maintain the boiler must be output in the use of the process, it is necessary to progress the fire-side temperature. Process outlet temperature of the furnace gas steam boiler making added, so it will make the loss of added gas steam boiler, reducing the heat transfer effect that it would be useful after fouling equipment in the water wall, so it is very likely Add water wall tube wall temperature can cause lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will reveal the original metallic tube, down to fouling. Secondly, in the incinerated gas steam boiler, furnace needs careful investigation smoke temperature and the temperature of the main steam changes; when the main steam pressure in the rising condition, if the boiler burning smoke temperature rise speed or does not rise significantly Pianman, immediately Check the oil gun fire situation.

Matters needing attention in loading and installation of Gas-fired Steam Boiler

Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.

1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.

2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.

3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.

4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
