The waste paper is divided into different grades according to the different product types, and then the waste paper can be produced and reused by pulping engineering. The production of waste paper pulp mainly includes four parts: pulping, screening and purification, washing and concentration, and bleaching. The production process mainly includes the dissociation of waste paper, screening and purification of waste pulp, deinking, pulp concentration, storage and thermal dispersion. Papermaking machine will improve the quality of paper by combining pulp and raw fiber, and re-manufacturing it into cartons, copy paper, etc. The processing plant will also purchase the base paper for processing according to the end use. These paper will be processed into cartons and packaging for daily use through different processing methods such as printing, coating, laminating, bronzing, die-cutting and pasting. In the production process of paper recycling, thermal energy support provided by industrial boilers is indispensable.

Industrial boilers have been the core equipment of the production line of paper enterprises. High-temperature steam provides heat source for cooking, drying and other production processes. A paper recycling factory in Uzbekistan is specialized in the reproduction of waste paper. A few days ago, the factory ordered a 2-ton WNS series gas fired steam boiler owned by Xinli boiler. This boiler is designed with large capacity,  sufficient steam storage space and heating surface, for ensuring high efficiency output of high-quality steam, and it can fully meet the heating demand of the production line of the plant. At the same time, the boiler uses the internationally advanced low-nitrogen combustion engine to easily realize the ultra-low emission of NOx, which not only effectively reduces the operating cost of the enterprise's equipment, but also fully conforms to the environmental protection regulations of many countries, achieving the purpose of energy conservation and emission reduction. The picture shows the delivery of the boiler:
