How natural gas 4 ton coal fired steam boiler in saudi arabia steam boiler model selection natural gas main type WNS and SZS type Both models can burn natural gas, liquefied petroleum gas, coal gas, coke oven gas, biogas, including steam boilers and hot water boilers, gas concrete how the selection of steam boilers, we take a look. Due to the different sectors of production processes, demand for steam boilers are also different, and therefore, when the gas steam boiler selection, need to have enough knowledge of the production process, in order to make the right selection and design of the boiler. 1, selection of technical parameters: gas comprising steam boiler rated evaporation, rated steam pressure, steam temperature rated, e.g., general pressure chemical production requirements are not too high, the pressure required to produce 10 kg as an example, then the boiler design pressure of 1.25 MPa is necessary to use; 2, ancillary equipment options: supporting auxiliary gas steam boiler main control cabinet, water supply pump, circulation pumps, burners, sub-cylinder, water treatment equipment, energy, a condenser, users can choose according to their own needs and price configuration; with the Earth's atmosphere deteriorating, I believe that we Chinese citizen environmental awareness is still very strong, in order to reduce pollution of the planet, we must first consider how environmentally friendly energy-saving performance, then consider fuel, gas boiler combustible gases, polluting emissions, environmentally friendly energy-saving ideas. Boiler pressures, consider the problems caused by an explosion caused by overpressure, and even carbon dioxide poisoning incidents. In the control of gas-fired boiler operation, select the better it is simple and easy to operate.
Jinzhou construction and installation company needs an electric heating hot water boiler house construction, after screening and comparison of various brand boiler industry, our excellent results in the cleaning of the boiler industry has been attracted to each other, in mid-2016, the Jinzhou construction and installation the company I signed with an electric heating pressure hot water boiler.
Steam boiler performance characteristics: 4 ton coal fired steam boiler in saudi arabia 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.
Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart.
