In recent years, the increasing popularity of Yichun City, Jiangxi Province comprehensive energy saving coal-fired boiler upgrade project, plans to eliminate 75% of the downtown 10 steam tons / hour and below the coal-fired boilers, a ban on new 20 tons of steam / hour and less fuel coal boilers; the rest of principle, then the new 10 steam tons / hour of coal-fired boilers.

Following this, Jiangxi Province Department of Finance issued a special subsidy fund boilers, Yichun downtown 2015--2016 phase-out 10 steam tons / hour coal-fired boilers companies grant. The subsidy standard is: 2 out of steam tons / hour and coal-fired boilers, subsidies to 10,000 yuan / Taiwan; out of steam 2-10 t / h coal-fired boiler, subsidies for 20,000 yuan / Taiwan.

Run time, and the thermal conductivity of the gas boiler gas boiler after its long run, inevitably its scale and corrosion problems in the use of the process, the main reason the gas boiler scale formation is due to the water with ingredients hardness, high temperature, high pressure continuously concentrated by evaporation. Gas boiler furnace in which it is running a series of chemical and physical reactions will occur during use will effectively form a dense and hard scale on the heating surface, which would lead directly to lower the heat exchange efficiency and due to corrosion under the scale factors, it will lead to reduced boiler water wall furnace heat absorption. The outlet temperature of the gas boiler furnace during the course of an increase, so that losses will increase in the boiler, it will be effective to reduce the heat transfer in the water wall fouling equipment, so it is very likely to cause the water-cooled wall tube wall temperature results in an increase of the thermal conductivity of scale squib gas boiler waterwall at runtime only a few tenths of a steel material, when its heating surface fouling, so that the heat transfer will be impeded, in use process in order to maintain a certain boiler output, it is necessary to raise the temperature of the fire side. During the washing process gas boiler which may be employed in an efficient and environmentally friendly non-corrosive cleaning agent for cleaning the boiler, so that the device will expose the metal tube primary colors, because the reduction of algae and biological sludge fouling effect. Note that after the need for effective gas boiler furnace during ignition of smoke was observed and the temperature of the main steam temperature, the case where the pressure rise of the main steam, which is encountered after the boiler ignition temperature of tobacco will significantly increase the speed of the smoke or temperature Pianman It does not rise to the herd to immediately check the oil gun fire conditions.

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.

Gas-fired wns fired steam boiler for hotel equipment maintenance equipment maintenance points 1: 1, or twice a day to clean up slag. 2, washed once or twice a heater dust (ash door with the appliance design) weekly. 3, once or twice a month, or butter oil feeding helical gears and bearings induced draft fan. 4, a monthly injection of butter or oil to the fan motor bearings once or twice. 5, a boiler must be 2-4 times the annual emissions (emissions must promptly after filling water). 6, poor water quality, in use. 2. Before, must soften water. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. Daily inspection equipment: 1, the fan regularly checks whether there is a feed screw loosening device, whether there is abnormal noise. 2, regular inspection trip tank float valve is normal replenishment, water pressure is normal. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass steam boiler, biomass hot water boiler, biomass oil furnace. 3, if equipped with a pump, replace circulation pump on a regular basis, and check whether the pump is working properly. Function gas boiler the ignition system that ignites the mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used Zhuoyi energy saving gas boiler manufacturers. Which facilitate saving, can simply press a finger, and safe, does not occur due to unexpected accidents occur flame, once the stall state occurs, the control system can close the solenoid valve, off the gas passage. 4, regular inspection equipment grounding cable is connected correctly. 5, to ensure the normal supply of fuel in the hopper, so as to avoid non-fuel flameout downtime. 6, it should be observed regularly combustion of the fuel in the combustion chamber. Incomplete combustion of fuel, smoke or large block to form sulfur, the sulfur should be promptly removed block and the governor to adjust the feed flow rate ratio of the fan, to achieve the desired combustion.
