gas natural boiler for coal mining

Gas natural boiler for coal mining safe handling as the country increasingly stringent emission standards for air pollution, the country has already started work boilers from coal to gas, out of heavily polluting coal-fired boilers, gas boilers using clean fuels. In this regard, Kono Tips boiler, gas boiler process, the need to pay attention to some safety issues: 1. burner to keep the working environment clean and dry, burner cleaning and maintenance once per shift to the control circuit must not get wet, affected by high temperature. 2. Check the electrical installations, mainly: whether the damaged wire, jacket damage, without loosening the screws, the contact is good, the motor is running any abnormal sound. 3. During normal operation, the burner portion close to thermodynamic device (such as a flange connection part) will be very hot, to avoid burns. Do not place near flammable materials, so as not to cause a fire. 4. combustor during startup, if the burner is locked repeated alarm reasons should be identified, and then identify failures and excluded press the reset button (pressing the reset button must not exceed 10 seconds), continue to start. 5. After the total gas pipeline experienced a temporary power failure solenoid valve (steel tile shed) to stop gas supply will automatically shut down until the first call burner electric alarm device to send, then a small hammer solenoid valve with total on hand to pull, you must first send electricity to manually open solenoid valve, solenoid valve will be closed and vice versa total. 6. fireman not mess-tune the burner, abnormal promptly notify management personnel, approved by management and then make adjustments. 7. In the long-term shutdown state, to do maintenance work on the boiler equipment, for each transmission parts to clean, lubricate.

AMD Power were to buy 10 tons of steam and one 4 tons of steam condensing steam natural boiler for coal mining fuel gas from the company for cell processing company production and construction. From the analysis of the demand to the boiler factory, by the company solely responsible for AMD Power fully demonstrated the company's confidence in me, the smooth progress of bilateral cooperation.

2.4MW YQW gas-fired thermal oil heater for textile industryThermal oil heaters play an important role in the textile industry, providing heat energy for the process of dyeing, drying and printing. Located in Manila (the capital of the Philippines), Pantone Finishing Corporation is a large company engaged in textile products. The rising in natural gas price results in the increases of running cost for original thermal oil heaters. In order to save cost while having no effect on production, the company planned to purchase several energy-saving thermal oil heaters. The thermal oil heater produced by ZOZEN has superior  advantages in manufacturing technique, which will guarantee the high quality. In consideration of the actual condition, ZOZEN’s engineer provided the company with YQW series gas-fired thermal oil heater and a tailored-made solution. The thermal oil heater adopts multi-loop coil tube design for safe operation, sufficient heating surface and high thermal efficiency. Furthermore,  to achieve maximum effect of energy saving and consumption reduction, the thermal oil heaters are also equipped with waste heat recovery device including heat recovery natural boiler for coal mining, air pre-heater and economizer. The textile mill was so satisfied with the solution that they ordered several thermal oil heaters.

2.1MW horizontal gas-fired thermal oil heater for chemical industryThe dyeing auxiliary is a chemical which enables a processing operation in textile preparation, dyeing, printing or finishing to be carried out more effectively, a natural boiler for coal mining provides stable heat source for its production process. Wuxi Kailai Biotechnology Co., Ltd., established in 2001, is an enterprise specializing in developing and manufacturing textile dyeing auxiliaries. The improving performance requirements for textiles lead to a largely increasing demand for dyeing auxiliaries. Kailai Biotechnology decided to obsolete the backward productivity due to the need of enterprise's own development as well as complying with the policy requirements of environmental protection, Kailai Biotechnology planned to order one set of 1.8 million Kcal thermal oil heater and use clean energy natural gas as boiler fuel.As one piece of important equipment of the production line, the thermal oil heater has a direct impact on the quality of dyeing auxiliaries and the benefit of the whole enterprise. After a series comparisons of boiler suppliers, the director of Kailai Biotechnology was deeply impressed by the large-scale, specialized and fine production of ZOZEN.Taking the actual working conditions of Kailai Biotechnology into consideration, the sales manager of ZOZEN provided one set of YQW series gas-fired thermal oil heater (YQW-2100Q) for the company. This series of thermal oil heater is equipped with an advanced low NOx burner, managing to ensure the full combustion of fuel and the NOx emission below 30mg/m3 ; in addition, the thermal oil heater adopts closed cycle heating, which has the characteristics of less thermal losses and remarkable energy saving effect; in conjunction with the energy-efficient equipment installed for the tail flue gas, the thermal efficiency of the heater can reach as high as 95%, the thermal oil heater is not only energy efficient but also safe.

Methane from Coal

In Pennsylvania, natural gas is extracted from coal as coalbed methane and as coal mine methane. Coalbed methane comes from virgin (unmined) coal. It rivals conventional natural gas in methane content and heating value with minimal processing. Coal mine methane is released from rocks associated with active or abandoned coal mines and is more variable in quality. Capture of this type of methane from coal grew out of the necessity to vent the gas from underground coal mines for safety purposes.
