natural coal fired steam boilers

The reason gas natural coal fired steam boilers flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. 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. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.

Details of operation of the boiler details chemical energy chemical energy Note 1 Note that operation of the boiler, fuel delivery is controlled with respect to the thickness of the layer of coal-fired boilers, the actual operation, the particles of different sizes on the same coal seam, unreasonable distribution, uneven ventilation, combustion is not uniform. The method can be employed uniformly stratified combustion to coal, to improve seam incomplete combustion: first administration of large particles of coal in the lower layer, the upper layer after administration minimal, large particle surface area of ​​small particles of coal, the need to burn a long time, this time is in the air the highest concentration of oxygen lower position; the other hand, small particles of coal on top, large surface area, a low oxygen concentration, full use of excess air. 2, the flow regulating damper excess air ratio is too large, a large loss of smoke; excess air ratio is too small, incomplete combustion loss is large, and therefore need to properly regulate the air flow to minimize loss of two or more. Usually in the flue gas analyzer backpass smoke, the control amount of wind of carbon monoxide is reduced to a reasonable value. For unconditional for gas analysis, empirical judgment by the naked eye can see the flame in the furnace, the flame pale described excess air amount; brown opaque flame, smoke black smoke indicates incomplete combustion. 3, there is a 1mm thick scale surface water quality management experiment boiler heating surface, waste of fuel from about 3% to 5%, in the presence of 3mm thick scale, waste of fuel of about 5% to 10% [3]. Water two general steps: pre-treatment, ion exchange or reverse osmosis. 4, cleaning blowdown gray scale or fouling deposition in the heating surface, increased heat resistance, reduced heat absorption wall, to improve the furnace exit gas temperature, boiler output decreased, but to increase the amount of cast coal, causing furnace exit gas temperature further improve a vicious circle. Therefore, timely cleaning clear dirt is particularly important. 5, the energy efficiency of the heat insulation testing industrial importance boiler showed small boiler in the case of good thermal heat radiation loss is about 3%, if the wrong selection insulation material, the thickness is too small, or even damage, does not include local heat, heat losses will be higher, the boiler has been running, has been caused by waste heat into the air. When the shutdown check whether the furnace wall insulation bricks off; isolated brick flue check is complete, to avoid shorting the flue gas; outer portion boiler, steam pipes and other insulation damage to be repaired; when heat insulation, low thermal conductivity of the material ( i.e., materials with good thermal insulating properties) on the inner layer having a better thermal insulation effect; respond to the economizer outer insulating layer for laying under conditions permitting. 6, to solve the problem of air leakage air leakage boiler boiler unit during operation is a common problem, the need to ensure the tightness of the boiler, furnace air leakage above all, do not close the site to check the furnace wall, door, inspection holes, etc., can be candles law, candles near these places, to observe whether the candle flame inward deflection to judge. Second leakage tail heating surface, the flue stack leakage mostly welding cracks, elbow bend, the expansion joints wear wear; mostly air superheater corrosion or wear leading to leakage through the pipe, the boiler shutdown should focus an examination.

SZL series boiler is a biomass boiler widely sold at home and abroad. CBM provides a 10 ton SZL natural coal fired steam boilers for a company in Tanzania. The SZL series boiler adopts advanced technologies and has many advantages. The 10 ton szl biomass steam boiler could burn biomass fuel, bituminous coal and others.

Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, natural coal fired steam boilers essential. Xinjiang Ake Su Xinnong Dairy Co., Ltd. as a local brand, has a large market users. 2016, Akzo increased demand for dairy production, the original steam boiler company can not meet today's production needs. In the same year, Akzo dairy cooperation with our company, signed a series SZS 6 tons of steam pipe steam boilers, steam support for the dairy industry dairy production Aksu.
