How to avoid the food processing enterprises boiler water pollution? How to avoid the food processing enterprises boiler water pollution? How to avoid the food processing enterprises boiler water pollution? It is well known in the food production process, many sectors need to use boilers, such as cooking, faced with the problem of sewage treatment, also with a certain level sterilization, dry, wine and so on. In the country's growing emphasis on environmental protection, continue to increase supervision of enterprises under the enterprise adoption of what approach to avoiding disadvantages, complete sustainable development? Primary, flue gas collection equipment processing equipment. Since SMEs by financial constraints, skills, and other places, a time can not be cut all the transformation, it is possible, after passing through the coal-fired boiler exhaust gas purifying exhaust purification device tail device, such as a fume hood, an exhaust gas collection processing device, effectively to prevent the direct discharge of black smoke, a serious impact on the surrounding environment. Second, clean power conversion, such as coal gas, coal to electricity. I learned that a beer factory invested more than 10 million will replace all coal-fired boilers, gas-fired. Now, 180 tons of coal powder steam boiler plant now farewell all coal, burning a low nitrogen gas cleaning switch, effectively reduce pollution. And compared with previous coal-fired boilers, coal saving more than 80,000 tons per year business.

Steam boiler performance characteristics: coal powder steam boiler Features: 1. Boilers faster horizontal fire tube boiler, refrigerant natural circulation. A boiler drum boiler heat exchange system, the left and right water wall header and composition, the main heating surface of furnace wall, part of the boiler tubes and boiler tubes in the convection tubes. This product consists of five main part of the boiler, flue dust, piping system. The first four members manufactured in a factory, can be transported to the installation site for assembly, shorten the installation period, to ensure the quality of the product installed. 2. Advanced Design Performance: main heating surface of the boiler 20 # low-pressure boiler seamless steel, special steel boiler tube boiler. Left and right header made seamless pipe. three. Boiler refractory concrete arch was destroyed. After another bow low and long, and it will burn well. Flue and side wall are made of bricks. Front and rear wall of the boiler use ordinary bricks made. 4. Exhaust flow and reasonable distribution of large combustion chamber, applicability coal. For a variety of bituminous coal or anthracite, mixed coal. very hot. High temperature flue gas enters the first settling chamber, and then into the flue wings from both sides, before re-entering the smoke box, smoke dust good effect. Simple water cycle, the compression pieces reasonable structure, safe operation of the premise of ensuring water quality. 6. The combustion apparatus is a fast loading grate, combustion equipment manufactured in a factory and installed, transported to the construction site may be mounted directly on the foundation. The present invention has a reasonable structure, compact, low steel consumption, performance, weight, size and structure of the boiler with the same capacity has significantly improved compared to the advantage of domestic products. Boiler work process: a substantially uniform coal particles by an automatic stoker coal thrown into the hopper, preheated before entering the arch in the case of rotating chain grate. Were burned in the incineration zone, fell into the slag pool. The high temperature flue gas produced by combustion of the furnace arch port into the furnace from a lower portion of the rear flue two wings, the wings and then heat the flue, through the forward flow before the packets enter the convection heat transfer tube bundle, then the tail tube boiler and dust entering the economizer section, and discharged to the atmosphere through a chimney to the induced fan. Boiler feed water is supplied by a boiler feed pump, demineralized water supplied by the economizer, and then enters the drum, and then enter the downcomer around header. Endothermic steam is generated by vaporizing water wall on both sides, into the steam within the steam separator drum, after separation, the main steam valve into the process heat required.

To enhance the thermal efficiency gas boilers What environmental policy: the combustion efficiency of combustion represents the degree of complete combustion. To improve the combustion efficiency of gas boilers and environmental protection, we must try to adjust the combustion conditions and better organization of the furnace, fuel combustion, reducing q3 and q4. Gas boiler environmental protection reduce exhaust gas temperature: at present China's industrial boiler flue gas temperature is high, is one of the main reasons of the low gas boiler thermal efficiency and environmental protection. Each small boiler flue gas temperature decreased 15-20 ° C, 15 ° C decreased every large boiler, a 1% increase in the thermal efficiency of the boiler gas. Accordingly, to try to reduce exhaust gas temperature flue gas heat recovery, reducing heat losses q2, the fuel savings. Softened water supply and condensate recovery: boiler feed water softening treatment and condensate recovery measures is to improve the thermal efficiency of the boiler. Raw water contains various impurities and fouling material, if not the water treatment boiler fouling. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, gas boiler output decreased to increase coal consumption, reducing the thermal efficiency of the boiler. Boiler keeps running at rated load: When natural gas boiler overload, due to the amount of fuel to be increased, the coal seam thickened, grate speed, air volume must be increased to meet the increased load required. Thick coal seam and grate faster incomplete combustion of the solid increase in losses due to increased air volume, the short residence time in the furnace flue gas, some burning of combustible gas has not finished on the drain with the flue gas, so incomplete combustion gas heat loss is increased. Meanwhile, when the overload operation, since the furnace temperature is increased thickening seam, exhaust gas temperature increase accordingly, so that heat loss is increased. Boiler low load operation, the amount of reducing gas, the furnace temperature is lowered, deterioration of the combustion conditions, incomplete combustion loss q3, q4 is also increased. When the boiler load is only 50%, due to a significant reduction in temperature in the furnace, it is difficult to maintain stable combustion furnace. Low load operation relatively increased heat loss, the overload or low-load operation the boiler will result in reduced thermal efficiency of the boiler. Strengthen the insulation, sealing, anti-leakage, anti-risk: Due to the wall gas boiler, soda temperature heat pipe system is better than the boiler room air temperature is high, so that part of the heat pipe system and soda furnace wall to radiation and convection to the loss of ambient air, heat radiation loss becomes the boiler. Only the furnace heat of the heat loss, reduces the temperature of the furnace at the same time, it affects the combustion. Therefore, the use of advanced insulation materials to strengthen the walls and heat insulation boiler pipes, reducing heat loss and improve the thermal efficiency of gas boilers and environmental protection.
