If within the natural gas boiler wear how to do? Off If there is detailed examination within the natural gas boiler wear how to do? Detailed examination is the key, fuel management is equally important. According to health and time natural gas boiler, we can plan a reasonable wear health check. When using the fuel, we strictly control the particle size of coal and limestone. Should strictly control the size of the bed material. Boiler waste should be handled. Boiler slag to be treated before discharge. Natural gas boiler should be installed in the heat of use, ease of installation. Hot water pipes should not be too long. It should have a good insulating layer. Hot water output to the end of the pipe should be suitably inclined. A water supply source should be equipped with a control valve. Of emissions, natural gas boiler chimney should extend to the outside, the outlet should be higher than the boiler 1.5 to 2M. If you want to reduce the impact on water wall tube, air pressure and air volume can be adjusted appropriately, effectively reduce the wear and tear of the water wall. Check the standby time is generally down or stop. To check items include leak wear, sealing the furnace and the furnace wall of smoke. In the event of wear, the need for timely repair and welding, to ensure the normal operation of the 4t h lpg fired steam boiler coal boilers supplier. In general, before the gas-fired combustion of fossil fuels need to be filled in the combustion chamber, fossil fuel and bed material and recyclable materials in air speed, strength and stiffness of the shed fully integrated. Wind bottom means upwardly within the core region. Movement of the outer annular region of downwardly along the walls of the flow of boiler water, thereby prolonging the residence time of the coal particles in the furnace. Mineral particles, large amounts of ash and flue gas contains large amounts of fly ash particles, which continue to cause rapid wear of the water wall tube, wall thickness wear thin, resulting in wear and tear.
Run chemical plant boiler problems that may arise is what chemical plant boiler operation possible problem is? There are two main chemical plant boiler evaporation: evaporation and rated maximum continuous evaporation. When the chemical plant boiler load is higher than the maximum continuous evaporation, it indicates the operating force or overload. The following problems may occur super-load operation: Main results are as follows: (1) due to increased fuel consumption, furnace volume heat load increases, the furnace temperature and furnace flue gas outlet temperature, resulting in the superheater and reheater the superheated steam temperature and wall temperature, and must therefore be strictly monitored and adjusted. Try not to let this time overheating. Coal furnace, furnace volume due to the increased thermal load, increasing the likelihood of slagging. (2) the flow rate of chemical evaporation apparatus system working fluid increases, the flow resistance is increased, it is not conducive to water circulation. Therefore, we should pay particular attention to the monitoring of the water cycle bad area. (3) the pressure differential between the drum and the superheater outlet flow increases as the working fluid and superheater flow resistance increases, so that the pressure of the steam drum and headers increases, the strength of these components must be considered . Space volume load (4) the steam drum, the load increases the evaporation surface, saturated with water vapor would increase, thus affecting the quality of steam. (5) chemical plant boiler safety valve Total displacement designed according to a maximum continuous evaporation. If the chemical plant boiler overload, once the sudden load shedding, the safety valve will not fully open, the steam pressure can not be reduced quickly. At this point, it is necessary to ensure the safety of the boiler by chemical vapor released into the air exhaust valve. (6) With the increase of the amount of air required for combustion and the amount of smoke produced, once sufficient air supply, the air volume is insufficient, the chemical conditions affecting the combustion boiler, increasing the likelihood of slagging; In addition, since the flue gas velocity the increase in fly ash increased the degree of wear of the heating surface. (7) during operation, the exhaust gas temperature rises, the exhaust gas heat loss; shorter residence time in the furnace the fuel, incomplete combustion heat loss of mechanical and chemical incomplete combustion to increase the heat loss, reduce the thermal efficiency of the chemical plant boilers. In summary, the excess chemical plant boiler operation have an adverse impact on the security and economic, should generally not excessive run. If the special emergency must also be strictly limited scope and excess power beyond the time required to force.
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.
Distinction gas 4t h lpg fired steam boiler coal boilers supplier and a conventional coal-fired boilers and gas steam boiler (1) in a conventional coal fired boiler should be prechamber through grinding equipment, coal should be produced for combustion injected into the furnace, the entire combustion process in furnace and in the form of a suspension. (2) as long as the gas steam boiler biomass fuels open, dried and crushed, the helical feeder to the air before it is blown into the top of the combustion grate vibration. After burning the soot removed from the baghouse gas steam boiler. 2, different air supply preheating. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees (1) coal-fired boiler air preheater flue at the bottom, below the economizer; using flue (2) temperature of the air supply end of the cigarette is heated, different from a conventional boiler, the feed gas steam boiler air preheated by the air preheater flue gas cooler and the two parts to feed water as a medium to absorb heat of the flue gas, conveying air into the furnace. Warm air supply system for a gas steam boiler is controlled by adjusting the supply air temperature of the heating water flow can be provided by adjusting the electric charge of the bypass track circulation water through the valve and the air preheater flue gas cooler bypass control. Water heat exchange section, cooling water heated through the air preheater and the cold air delivery fan; then, this part of the water continues to flue gas cooler, flue gas by exchanging heat with water in the flue gas cooler, water heating, cooling the flue gas. In the bypass, a bypass flue gas cooler and another bypass air preheater, both have their own electrical control bypass and isolation valves. When the flue gas cooler exit gas temperature is too low, the bypass isolation valve is opened, water does not pass through the flue gas cooler, flue gas heat exchanger is not performed to ensure the flue gas cooler outlet gas temperature is not too low smoke corrode gas cooler. In order to enter the flue gas cooler feedwater temperature is not too low, when the air preheater outlet water temperature is below a certain temperature, it opens the bypass, supply cool air can not be heated, the water temperature is too low to prevent the influence of the flue gas cooler work . But also to ensure the temperature of the flue gas through a gas steam boiler precipitator. 3. The coal-fired boiler flue gas fired boiler bag filter should be used for desulfurization libraries to ensure the emission of pollutants lower than the standard. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. 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. However, biomass combustion flue gas are different. Biomass fuel of low sulfur and nitrogen content, only through the biomass filter before discharge into the atmosphere. However, the carbon content of fly ash produced by the combustion of biomass, coal-fired boiler boiler efficiency is better, but the carbon dioxide content in the greenhouse can be reduced. Under the same nitrogen content of the fuel, the nitrogen oxides emission concentration of boiler far below the emission standards for coal-fired boilers. The problem should be noted that operation of the gas boiler. From the operational perspective view of the gas boiler, the operation of the gas boiler should note the following: The actual fuel consumption of the boiler operation, the amount of oil to the adjustment screw feeder. Unburnt fuel in the furnace, induced draft fan and the blower can not be stopped. Sudden power outage in operation, must be promptly removed fuel furnace. Not add biomass fuel before the shutdown. When the furnace stopped, there is no need of the bank up a fire. When the fuel on the grate exhausted, drum induced draft fan may stop running.
