「The objectives and challenges of future research and development activities are as follows. (Research and development objectives) 1) Adaptation of the JSA bi-fuel burner to preheated air and development of a range of capacities. 2) Development of a radiant tube burner using ammonia or hydrogen as fuel. 3) Performance improvements to the existing HRS-RT burner.」
The conversion to gas fuel for high-temperature kilns used to fire ceramics, which was suspended for the time being in the prior fiscal year, is not included among the current fiscal year's research and development objectives and challenges. - FY2023SoftenedAnnual report
「Development of the fuel conversion from oil to gas for burners used in high-temperature kilns for firing ceramics had been led by the customer, but has been suspended for the time being. We are preparing so that we can respond promptly when the study resumes.」
The gas-fuel conversion demonstrated at a commercial facility in the prior fiscal year has been suspended for the time being, and the project has regressed to the preparation stage for a possible restart. - FY2022AdvancedAnnual report
「For kilns used for high-temperature firing of ceramic materials, the company attempted to convert from oil to gas. Testing conducted at a customer's commercial facility in April 2021 demonstrated that products meeting the required standards can be fired even after converting to gas fuel.」
Testing at a customer's commercial facility demonstrated that firing products meeting the required standards is possible even after converting from oil to gas fuel. - FY2021SoftenedAnnual report
「The effort to convert the fuel used in kilns for high-temperature firing of ceramic materials from oil to gas is scheduled to resume in fiscal 2021.」
The conversion to gas fuel, which had been scheduled for completion and operation during fiscal 2020 in the prior fiscal year, has been pushed back to a planned resumption in fiscal 2021 due to delays in the experimental study. - FY2020AdvancedAnnual report
「Demonstration operation using an actual high-temperature kiln for firing ceramics showed that it is important to match the combustion conditions of the gas-fired burner with the kiln operating conditions required for proper firing. The company determined that optimal firing can be achieved by making this match appropriately, and has brought the project nearly to completion. Completion is scheduled during fiscal 2020, followed by operation at a ceramics manufacturer.」
The demonstration operation for the conversion to gas fuel confirmed the optimal firing conditions, and the project had progressed to near completion. Completion and operation during fiscal 2020 were also scheduled. - FY2019First statedAnnual report
「We have begun efforts to convert the high-temperature kilns used to fire ceramics from heavy oil, which has traditionally been the primary fuel, to gas, in cooperation with a gas company.」
The company has begun efforts, in cooperation with a gas company, to convert high-temperature kilns used to fire ceramics from heavy oil, the primary fuel, to gas. Applying gas fuel to high-temperature kilns operating at 1,700°C or higher is also listed as a key challenge.
